D's supposed to be a more modern replacement for C++. One thing it has got going over other languages is its metaprogramming capabilities, with mixins, static if, template constraints.

>>56048754
> static if

why do you need a hack like this if you have metaprogramming

>>56048803
How the hell is that a hack?

Let's say I wanted to write a forum software.
Would I leave my CGI script at the root of the website and have all URL queries, such as /g/thread/52676882 be tokenized within the CGI script?

Or am I going about this all wrong?

>>56048832
is D metaprogramming handled at compile-time?

Lisp has proper metaprogramming and you don't need a "static if", you just evaluate an if-expression (or any other kind of expression) at compile-time.

e.g.

;; dumb example 
(defmacro macro-fib (n)
  ;; whoa, static-if!
  (if (< n 2)
      n
      `(+ (macro-fib ,(- n 2))
          (macro-fibs ,(- n 1)))))

(mac-fibs 8)

;; expands to

(+ (+ (+ (+ 0 1) (+ 1 (+ 0 1))) (+ (+ 1 (+ 0 1)) (+ (+ 0 1) (+ 1 (+ 0 1)))))
   (+ (+ (+ 1 (+ 0 1)) (+ (+ 0 1) (+ 1 (+ 0 1))))
      (+ (+ (+ 0 1) (+ 1 (+ 0 1)))
         (+ (+ 1 (+ 0 1)) (+ (+ 0 1) (+ 1 (+ 0 1)))))))

Dark C++ show me the dark metaprogramming

any opengl or graphics bros out there. Trying to make a model viewer for a particular file format but for some reason I cant calculate the final position of the vertices properly. I know what the final position is, but it doesnt make sense given the weights and bone matrices.

>>56048959
Not him but D's static if is something like pre-processor directives in C and C++ to control compile time conditions. If you're looking for something equalivent to your code then you can use a mixin to generate a chunk of string and have it interpreted as an actual piece of code. Unless I misunderstand what you're discussing here because I've not followed the discussion.

>>56048959
Yes, it's for compile-time
Like a better C/C++ preprocessor
https://dlang.org/spec/version.html#staticif

More on the mixins if you want to see that
https://dlang.org/mixin.html

Go is the worst language if you use it I hope you like writing the same code over and over again because it doesn't allow for literally any kind of abstraction, it's almost like it was designed for people who aren't capable of using a normal programming language.

>>56049052
just saying that needing a special 'static-if' makes it seem like you've got a hamstringed metaprogramming system.

>>56049065
That reminds me a few threads ago someone mentioned the Zebra Puzzle and I looked up solutions on Rosetta Code, both Go and C were pretty damn disgusting compared to other solutions.

this isn't just useful for junior devs, though.
in fact, most devs aren't researchers, and the current languages at the front of research aren't yet particularly useful for anything practical (and their communities make the exact mistake that go is attempting to prevent its junior devs from making: premature and excessive abstraction).

when you guys have an idea for a program, or software to write, or even tackling one of the many programming challenges that get posted on here daily, how do you handle implementation? I mean, how do you decide what data structures to use, what algorithms will be useful, what patterns could come into play, etc...

is it something you should know in the planning / idea / design phase? or is it something that you think of as you are coding it?

I'm always worried that I'll try one of these challenges, and I'll end up getting it to work, but in a really hacked together, inefficient sort of way. Am I really learning anything by doing that?

>>56049404
"company culture" is the biggest cancer meme

>>56049320
your provided link is confirming my argument.
a statically typed language that provides the tools for easily implementing map/filter/reduce also provides the tools for people to quickly go batshit with abstraction (especially with types).
go makes it hard to abstract a lot.
this means more code duplication, but also more explicitness and less premature abstraction.
i'd argue that overall it's nicer for maintainers to read more explicit code (as they don't have to learn layers on top of layers of abstraction for every single thing and every single dev working on the project), but more annoying for devs to write the code.
haskell is one of the most powerful of the more popular statically typed languages, and it suffers from extreme amounts of premature abstraction.
go certainly isn't as fun to write as haskell, lisp or even python, but i'd argue that maintaining a go is quite a bit easier.

I just finished the Rust tutorial. I haven't used it yet, but it looks much better designed than Go. My biggest problem with Go is the boiler plate error handling. The Rust Result type looks much more interesting.

>>56049587
There really is no difference between an option type and returning two variables.

Both are effective replacements for exceptions everywhere.

>>56049660
>make a different but equivalent syntax for exceptions
>call it an effective replacement

>>56049660
It's hard to test the cause of the error in Go. You either have to use sentinel errors or wrap the errors in your own container. It feels like error codes in C, which are bad for general use.

>>56049697
they're not equivalent to exceptions, neither of them
only once you introduce monadic control flow to option types they become similar to exceptions, and even then, in the case of monadic option types they're still different from most exception implementations in the regard that they're actually explicit at compile time
it's debatable whether monadic control flow is a good thing in imperative languages, as it usually hides some sort of information that might be important for the reader.

>>56049652
nope, just saying that code duplication goes against maintainability, as does improper or insufficient abstraction.

trying to improve maintainability by not allowing abstraction is extremely retarded, for so many reasons that i'm not even sure where to begin.

>/dpt/ tells me that webdev is babby shit
>go into webdev

you lied /dpt/, I never asked for this

>>56049756
in both rust and go, if you want errors to both carry a context and be distinguishable in regards to their nature, you need to define an error type that contains that context.
in go you use a type assertion switch to unwrap the error into its concrete context type at runtime, while rust allows you to do this at compile time via pattern matching.
that's the only difference.
as go has no generics (which yields the advantages and disadvantages i mentioned at >>56049481) pattern matching wouldn't make much sense either.
both implementations (and exceptions as well) have a hard time when hand crafted context should get added at every layer, effectively resulting in a chain of errors, with each layer still being identifiable.

>>56049788
if you really believe that every dev should strive to achieve maximum DRYness then i feel sorry for your coworkers.
sometimes, duplication is better than abstraction.
this is a well known fact.

alright, the general statement

made it seem like you were.

go doesn't *prevent* abstraction, it just makes some kinds of abstraction harder, trying to push people more towards the optimum from the other side of the spectrum.
if people still persist on prematurely abstracting, even with those limitations, then the result will be incredibly ugly.
i haven't seen any cases in go projects where this was an actual issue, though.
people don't abstract that much and many people have found that to be more readable.

by the way, C attempts that in some ways as well, but fails in other regards with this approach, so there are still more opportunities to fuck things up (macros, for instance).

>>56050313
>if people still persist on prematurely abstracting, even with those limitations, then the result will be incredibly ugly.

Languages can't prevent "premature abstraction", they either allow certain abstractions or do not (or only in a ad-hoc interpretive manner).

Go does not allow certain abstractions even whey they are determined to not be premature.

>>56050313
Code duplication DOES go against maintainability. I should never have to repeat myself to the compiler.

There is no such thing as premature abstraction. The more abstract your code, the easier it is to reason about. I can tell you what

hurr :: forall a b. a -> b -> a

does, but not what

durr :: Int -> String -> Int

does. Go does indeed prevent this sort of abstraction.

>>56050313
>it just makes some kinds of abstraction harder
Not him, but the lack of generics prevents you from reusing your data structures.

>>56049457
>I'm always worried that I'll try one of these challenges, and I'll end up getting it to work, but in a really hacked together, inefficient sort of way. Am I really learning anything by doing that?

Well yeah I think so. When I do these it's usually pretty ugly. Hacky and inefficient is what learning looks like. It could, be that you're trying to find a workaround using only what you already know, but ideally it should be difficult enough that you have to learn at last one new thing to make it work. The next step is to clean it up or look at how others have solved it.

If your program is super clean and perfect first try, it's probably because you did something you're already really comfortable with and therefore learned nothing. Rolling btw.

I've been working on CS50 Problem Set 1 and my code for the greedy script where you are supposed to find whats the least amount of change you could give back to someone has been giving me weird results like putting in .41 gives you 3 when it should be 4. I've tried a lot, but I can't get it to work

#include <stdio.h>

{

    int coins = 0;
    float owed;

    float dime = 0.1;
    float nickle = 0.05;
    float penny = 0.01;
    
    // Get change
    printf("How much change is owed?\n");
    owed = GetFloat ();
    
    // Math
    while (owed >= quarters)
    {
        owed = owed - quarters;
        coins++;
    }
    while (owed >= dime)
    {
        owed = owed - dime;
        coins++;
    }
    while (owed >= nickle)
    {
        owed = owed - nickle;
        coins++;
    }
    while (owed >= penny)
    {
        owed = owed - penny;

>>56050378
i guess i'll agree with you on that.
there are some areas, especially in regards to types, where it's a lot easier to go overboard with abstraction than say through functions alone, and you don't notice as quickly, though.
iirc reputable fp people like erik meijer have started doubting the benefits of generics as well.
that being said, go made the argument about duplication and explicitness over abstraction more popular again (i know that sicp mentions it as well), so that's a good thing.
stuff like gofmt and other parts of the tooling are also pretty awesome, and i hope other new languages adopt some ideas from that.
the same goes for the gc.
build speed is also a good thing, in addition to the entire argument about abstraction.

Erik is just butthurt because he didn't get his way regarding Foldable/Traversable being added to the prelude. "It makes teaching Haskell harder!" Use a different prelude then, dumbass.

Generics are useful for a lot more than just containers, especially when paired with typeclasses.

>>56050384
>The more abstract your code, the easier it is to reason about
would you say the same about abstract factory factories in java, or is that somehow a special exception to your magical and absolute rule?
what about c++, where most users use different subsets of the language, resulting in a mess when many people work together?
in fact, what about haskell, which suffers from the same problem but at a way greater scale? the last time i checked different people were handling errors in 10 different ways, and that's just error handling!
i don't think i've talked to a haskeller irl before that wasn't complaining about working with the code of other people that use a completly different set of abstraction than them.
maybe you're the first one?

>>56050566
>he doesn't know that currency floats

top pleb

>>56050597
Yes, I would. If something takes an abstract factory, then in a perfect world you know it doesn't depend on any details of concrete implementations. Unfortunately Java allows you to circumvent its generics with instanceof and reflection.

I know Java best when it comes to GUIs and graphics etc. but I hate the language.
I like Racket but I've never done anything with graphics in it before.
I love Haskell but game development is much harder in it.
I like Python but I feel like I'll spend more time on learning the framework than doing actual game programming.

Also rate my code: https://github.com/Wysaard/fucked-up/blob/master/fucked-up.c https://github.com/Wysaard/braiell/blob/master/Main.hs

>>56050742
it's not
~/.emacs brings up nothing
~/.emacs.d brings something up
and doing ls -a only lists the emacs.d
which is just a directory
ctrl+h, v with "user-init-file is a variable defined in ‘C source code’." yields back the result ""/home/.emacs""
it's truly fucked bruh

>>56049457
>I'm always worried that I'll try one of these challenges, and I'll end up getting it to work, but in a really hacked together, inefficient sort of way. Am I really learning anything by doing that?

You'll learn from the criticism. Only problem is that on 4chan you don't know whether you're talking to an expert or an imbecile.

Sorry to bother you programmers-sama, but I have a question, maybe you could help me. Consider a situation where you don't have a lot of time and you're already middle-aged but want to change careers. What would be the safest and fastest way to go? What branch/language should I learn by myself?

>>56050774
do you think the same goes for user interfaces? that a user interface (e.g. a CLI interface) without any duplication is better than a user interface with some duplication?
what about natural language, would it be easier to understand if we defined a load of "language macros" that people will have to remember when speaking? use acronyms for everything i'd otherwise have to repeat in some way?

>>56050853
Irrelevant. We're talking about writing code here.

>>56050810
I wanna do some gamedev for fun too, but I have no idea what to make.
Anyway, about languages, despite hating Java as a language too, I personally found it good for getting something up and running quickly.

>>56050842
you have to give more info.

what current field are you in? is it related to programming ?

>>56050853
> what about natural language, would it be easier to understand if we defined a load of "language macros" that people will have to remember when speaking?

this is what happens already though
slang and new words are created all the time

>Bought C++ Primer from Amazon

Should I continue? What does the future hold for me? Programming is hard, bros.

>>56050824
~/.emacs.d should have an init.el file which is roughly the same as a ~/.emacs file

>>56050430
Try using doubles, floats are really imprecise. They're mostly useful for when you need to approximate decimal values.

>>56050885
code, something being read, is in that regard not any different from a user interface or natural language.
if you don't think it'd be a good idea for things like language or prose, why would it be a good idea for code, something else that is to be read and understood, just like prose?
sure, if you're arguing that the only thing to read your code is the compiler, then that's correct, but that isn't the reality.

What's the easiest way to load/save two lists with a single file in C#?

>>56049457
how do you decide what data structures to use, what algorithms will be useful, what patterns could come into play, etc...

Try to reduce to program to certain pieces, look at the necessary things to do and what's most efficient. It's kinda an abstract notion but it hard to explain globally. There are just some general rules (lots of insertion, no random access needed = linked list; lots of random access, no insertion = array, some random access, some insertion: hash table / tree / some ad-hoc implementation of an arraylist)

>>56050899
Not at all. Starting from scratch.

>>56050935
but that file is empty...shouldn't it be filled with the defauls?

>>56050936
doubles are still imprecise, not sure if they're TOO imprecise for this specific task, but for currency you should definitely use integers

>>56050924
>Should I continue?
Of course.
>What does the future hold for me?
No idea.
>Programming is hard
It can be. What're you struggling on, anon?

>>56050952
i'd guess that the defaults are just built-into emacs, what are you trying to do?

>>56050917
yeah, but there is still a lot of duplication, because getting rid of all the duplication would be horrendous
language changes over time, that's normal.
things get slang words and abbreviations when they are duplicated a lot, just like in code, when it makes sense to abstract something when it is duplicated a lot, as opposed to just once.

>>56050952
>>56050935
no wait, no that's a seperate file
the only things listed are
auto-save-list
and
ede-projects.el
NO init.el file

>>56050842
Anything that you like to work with? As in, are you interested in mobile, web, networking, 3d graphics, etc. Or whatever is easy and fast to get into?

>>56050888
Yeah that's the appeal of it to me. I know that I can at least implement a proper game engine quite quickly. As far as ideas go: I'm going to try making something roguelike, but also with some arpg elements. I also have an idea for a story but I'm a bad writer so I'll have to figure that out.

>>56050948
how old are you, if you don't mind asking?

>>56050842
Python is a good first language. If you want graphics on your screen fast, Java can be very nice.

In the end though, your language of choice will depend heavily on what you're going to do. For example: if you're gonna do web make sure you know JS and PHP, maybe Python if you want to work at a younger company. However, if you're not gonna do web, learning those languages (except for Python) is 100% a waste of time, nobody likes JS but it's popular in web, and PHP is only useful in web.

>>56050982
Just the fastest and most efficient way honestly.

>>56050566

Sorry, the problem set says to use floats, so I did

>>56050810

>>56050853
> would it be easier to understand if we defined a load of "language macros" that people will have to remember when speaking? use acronyms for everything i'd otherwise have to repeat in some way?

That's exactly what's happening on the internet though. The sheer amount of internet slang and abbreviations that are constantly being invented is staggering.

>>56051033
Thanks. Maybe Python is a good option then.

Kinda unrelated but is cybersecurity hard and how would you start learning for this?

>>56050936
Actually it would be better to use ints. Doubles are more precise than ints, but you'll just end up being a quadrillionth off instead of a billionth (metaphorically of course). Just save the amount of cents instead.

>>56051083
that just means to paste that code in and replace the paths with where scheme is installed

>>56051064
still not enough to avoid complete duplication, though.
it doesn't even remotely reach the point of "abstracting every single duplication" as mentioned by that other anon.
also, having read a lot of ee-related specs in my life time, those sometimes go overboard with "abstraction" in language.
i'm fine with some clear definitions at the start of a paper (note: sensible abstraction), but those go completly overboard sometimes, and i gotta spend ages looking shit up

>>56051061
Did a little debugging, on my PC actleast the penny while isn't firing.

This is obviously because of a rounding error. This is why you don't use float for money.

>>56051113
The problem set says to use floats, so I did

>>56051087
What about decimal?

>>56051053
All right so, the fastest way I've seen someone get into coding is with JavaScript.

The reason for this is that it's a very simple language to learn and get into, though it does have some obscure things and very retarded design decisions at some parts, but nothing that you can't learn or that will affect you as you work your way through the language.

You can learn it in about 1 week and start to do something with it.

It also has a ton of demand for web, and some for backend shit with NodeJS. It pays anywhere from decent to stupidly high depending on where you look.

The BAD thing about it is that whatever you learn in JS will not translate to most other languages. If you want to get into C++, C#, Ruby, Python, etc. later, you will be learning almost everything from scratch. If you learn one of those languages first, most concepts will apply to all object oriented programming languages later, and JS will look like a toy language by comparison.

If you're looking for a job, check out job positions in your areas of interest so you can get a better idea.

>>56051124
I understand that but the use of floats is actually what's causing your problem. Whoever set the problem up is an idiot.

Just make it somehow work and then work on making it better. Rewrite the code to be cleaner, optimize shit, think of how you could've done certain things better and do them.

your program doesn't handle floats

you can check how many digits a number has by doing

#include <math.h>

abs(floor(log10(number)))+1)

only simple solution is: convert your number to string, reverse the string, and convert the string to number again.

First I'm using the python image Lib to get the pixel RGB value. This value is formatted like (255,255,255) but in the video they are working with a singular value. what kind of magic can I do to get to something like that.

Second do my kernels have to be 3x3 blocks or can they be 10x10 or even larger?

Just do each of the RGB values separately. The video probably used 1 so that people could get the point easier.
>Second do my kernels have to be 3x3 blocks or can they be 10x10 or even larger?
They can be larger. Larger blocks will give you more of a blur.

Are file extensions case sensitive?

>>56053768
It was a cartoon in the 90s about three friends named ed they where always trying to save up money to buy jawbrakers

>>56053802
Depends, NTFS is insensitive, most other fs's are.

Been a while since I last messed with lisp so I'm doing sicp again to get comfortable.

#lang sicp
(define (sqrt-iter guess x)
  (if (good-enough? guess x)
      guess
      (sqrt-iter (improve guess x)
                x)))
(define (improve guess x)
  (average guess (/ x guess)))

(define (average x y)
  (/ (+ x y) 2))

(define (good-enough? guess x)
  (< (abs (- (square guess) x)) 0.001))

(define (square x)
  (* x x))

(define (sqrt x)
  (sqrt-iter 1.0 x))

Using racket so I don't have to screw around with too much.

Is Microsoft literally retarded?

>>56053377
You need to expand your leap check.

It should be something like

if(year%4==0 && year%100!=0 || year%400==0)

>>56053539
Your coding style...

/*returns 0*/
return 0;

>>56053927
could be confusing if you don't know what return means

>>56053935
return :: (Monad m) => a -> m a

>>56054040
Sorry Anon, but you appear to be using a meme language.

C++ question.

I have a pointer to an object. One of it's class members is a ponter to another object, a vector. What syntax do I use to access an index of that vector?

(*obj1).(*obj2)[3] doesn't work.
obj1->(*obj2)[3] doesn't work.
What is the correct syntax? I want to access it using the array syntax because it's faster.

>>56054130
I don't use C++ but have you tried obj1->obj2[3]. The array syntax should tell it that the thing in question is a pointer.

So out of practice with lisp it's not even funny. Any tips to improve the formatting?

#lang racket

(define (sqrt x)
  
  (define (square x)
    
    (define (double x)
      (+ x x))
    
    (exp (double (log x))))
  
  (define (good-enough? guess)
    (< (abs (- (square guess) x)) 0.001))
  
  (define (improve guess)
    (define (average x y)
      (/ (+ x y) 2))
    (average guess (/ x guess)))
  
  (define (sqrt-iter guess)
    (if (good-enough? guess)
        guess
        (sqrt-iter (improve guess))))
  
  (sqrt-iter 1.0))

an upperclassman told me I should learn python for my algorithms class. As it stands right now my best language is C++ so I'd be doing the class in that, but I'm sure it'd be very difficult; especially if hand-written data structures were involved. is there any merit to what he says? do you recommend another language? I think I can use any language.

>>56053927
That was when I started learning programming, I still like to comment my code (maybe a bit more than necessary) but now I keep comments at function definition level mostly.

>>56054183
C#

I'm more interested in the pic than the thread.

Call me /g/.

>>56054173
Don't use lisp.

>>56054183
Do you understand how pointers work?
If so, just use C++.

>>56054192
I know C# already but I don't use Windows so no VS. I'd prefer something I can use with emacs and terminal in linux; unless you have a particular reason why you'd recommend C#

>>56054205
Well I've been using C++ since I was 13 so I think I do.

>>56054183
Why not wait and see how hard the class is?

>>56054229
Jesus christ, that sounds horrible.

>>56054229
If you're that confident in your C++ skills, why do you think the class would be hard using C++?

>>56054209
>I know C#!
>doesn't know about .NET Core

Why would you tell lies on the internet?

>>56054163
That doesn't work I don't think? Because I need to dereference obj2 as well. My problem is even more complex, because it's a 2d vector, a vector of vectors.

I found the solution though.
(*obj1->obj2)[3]

>>56054204

Compelling argument anon. Why exactly shouldn't I start playing around with lisp / scheme again for hobby projects?

>>56054254
What the fuck is .net core? I use mono to run Chashtag application on Linux right now, but if .net core has all the shit I need and isn't as much of a bloated heap of shit I'll switch to that instead.

Fucking christ familias, I got it working for one second and then I decided to change the code to make it more readable and now it's completely broken.

http://pastebin.com/jEN3MckR

Well aware that the size parameter is redundant btw familias, it's gone in the version of the program I have on my PC but I couldn't be assed to make a new Pastebin.

The issue seems to lie in the for loop inside of the initialPurchase function. no matter what iteration of the loop it's on, a[i] never evaluates to anything other than a[0] until the last iteration of the loop, where it'll all of a sudden prompt the user to buy their misc supplies and then goto reset because it'd be impossible to spend less then 700 if you're not buying anything but oxen.

>>56054577
ohgod

Don't use goto.

Honestly there is so much wrong with that code I don't even know where to begin senpai.

>>56054619
Given the fucked up number of indentations that code has goto was actually a good idea.

>>56051606
The first website I learned javascript/python on was codeacademy, it has guided tutorials where you pretty much program on rails, which to me is its weakness, but it's good for beginners

>>56054577
>Using a GOTO

GOTO GTFO

>>56054619
>>56054665
>mindlessly parroting memes
Goto was literally the most readable option.

I want Dijkstra to leave

>>56054577
I mean no offense man, I understand everyone has to start somewhere. The code I wrote when I was first starting to learn to code was really awful.

But this is like bait tier levels of bad. I honestly don't even know if you're serious, or if you just put together something so awful as a joke.

I mean, I've never, ever ever seen someone use a do-while loop irl. Or goto. And why use if/else inside a for loop? If you remove the for loop AND the if/elses, and just have each do-while loop one after the other, your code would do the exact same thing.

>>56054696
>readable
>that code

>>56054696
>>56054709
Look at you trying to talk shit when your ass can't even write a simple loop properly

>>56054696
I'm not even lying, that is literally the worst code I have ever seen in my entire life. Don't try and talk about memes when you write at the level of a 10 year old.

Go back to scratch.

>>56054728
How can someone know who Djikstra is, and write code like that?

It's bait.

>>56054715

>>56054740
I just started programming less than a month ago, s-sorry if it's not up to your standards senpais.

I'm definitely open to suggestions thogh, and if my code is so incomprehensible that you don't even know where to start then I could explain what I intended for it to do step by step if it meant being a better programmer.

>>56054254
I mean I've used it at work and we certainly were not using Linux there. I found the language kind of boring and didn't do much with it at home.

>>56054577
Couple things friend.

Don't use bool in C, lowest level of memory you can address in C is 8 bits unless you use bit fields. In C always use char in place of bool.

Don't use goto.

Finally the reason your logic is failing is you're comparing the values of the elements in the array, not the indexes themselves.

It should be if(i==ANIMALS).

>>56054253
>>56054253
sometimes even then there are easier ways

>>56054785
I understand each step of it. I know how all the structures work. But you've combined them in such a confusing and redundant way.

To start with, that for loop and those if else statements are redundant. Your code would have exactly the same effect if it were just one do-while loop after the other.

Also, why do-while? I have personally never used a do-while loop, they are confusing and weird. Would be much simpler as a while loop.

So I've created an Android game app, and the game play and menu screen layout is copied from another app.

The game play I've copied is the way the character jumps, and the way the platforms and obstacles spawn.

Everything else is different, and I've written all of the code myself.

Can they get me removed from the Play store? Or will I be fine?

Do the programmers here who learned diy, how long did it take before you got a job? How did you justify your skills?

>>56054876
Depends, did you decompile and steal their source? Or did you just imitate the look a bit. As long as you aren't using trademarks or copyrighted names, you should be fine.

Not familiar with the Play store myself, but isn't it rife with clones anyway?

I learned on my own for a year, did one year at a university and then got offered a job. At uni we mainly focused on OOP concepts, which I hadn't really done much of on my own, these were super useful when working, learn them.

I was working there for an internship over the summer at first, so I guess I proved myself by being competent and productive during that time. Didn't really prove anything to get the internship, just said "Yes, I can program".

>>56054964

Do you recommend any books on programming? Not any specific language but methodology in general? I only Java and a few libraries. I always find myself asking myself how. I don't think it's a lack of Java knowledge, but a lack of OOP and general programming methodology knowledge.

I have an #ifndef in the header file that defines bool as an int8_t, is there still good reason to use a char instead? (believe chars are the same size on most systems, and the stdint library is ANSI standard)

You're completely right about the logic of my code though, forgot to assign the value of moneySpent to the element in the array addressed by the if/elif statement so every element has a value of zero. Therefore every element in the array is equal to one another so the first if statement always evaluates to true.

>>56054833
I d-don't know why I use do-while familia. Is there a neater way to keep pestering the user for input if they enter something unreasonable?

>>56054912
I imitated the look. I haven't even downloaded their APK.
There's only 2 randomly generated walls, 2 randomly generated cubes, and a diamond.

But I used tracing paper on my phone screen to compare both apps until I got the spawning exactly the same.

I guess I shouldn't have to worry, as you're correct that there are a ridiculous amount of clones

I don't get how one is supposed to cross-compile using the cross packages from some random ubuntu PPA....
has anyone used this shit? how the fuck do you compile mips shit from amd64???

>>56054760
>otherwise it looks ok although i prefer the one with just a nested loop where you choose the character based on if the variables fit the lines' mathematical equations like y == x etc

You would be amazed at what happens when someone who has a degree in math decides to go to grad school for computer science.

>>56055013
>I have an #ifndef in the header file that defines bool as an int8_t, is there still good reason to use a char instead?

Not really, so long as they aren't the bool type that was included with the 1999 standard.

>SICP

Full of autism, but good read.

>We are about to study the idea of a computational process. Computational processes are abstract beings that inhabit computers. As they evolve, processes manipulate other abstract things called data. The evolution of a process is directed by a pattern of rules called a program. People create programs to direct processes. In effect, we conjure the spirits of the computer with our spells.

lmao

>>56054981
How much oop have you done? Once I had a general understanding of how oop works in Java, I just started reading about different design patterns. And writing applications that used them.
If you want a book that's really great (but Java specific), check out "Thinking in Java". It covers a large amount of the useful stuff in the api, and uses good Java programming practice.
Didn't really read any book specifically other than that though.
Playing around with C# isn't a bad idea either, as lot's of Java skills carry over. Lot's of companies are using C# for crud business applications, so saying "Yes I know C#", even when most of your knowledge is in Java, is a good idea.

>>56055001
Fuck SICP. If you wanna do academia for compsci, go ahead, great book as an intro. But to actually go out and get a real job? Nope. It's also sorely lacking in any kind of object oriented stuff.

>>56055013
I don't know if it makes any difference in how terrible my code is in general, but I'm trying to stay as true (functionally speaking) to this >>56053195 as possible.

Would appreciate any and all constructive criticism you still have (though I would really appreciate if you reimplemented the function in a more sane way so I'd know how somebody who isn't me or Pajeet would do it)

>>56055013
Just use a while.

while(moneyToSpend < 200 || moneyToSpend > 300) {
    // Your stuff here
}

Do guaruntees that the loop will happen at least once, even if the condition is not fulfilled.

If you are trying to stay true to that code, all you are going to do is translate that logic into C. It will be longer and more complex than necessary, but I guess it's doable.

If you want to do it well though, try and rewrite it in C without using goto. You should be able to use C concepts (if/else, loops, etc) to do everything in that code without using goto.

Can't speak for most of those, but since Clojure is a Lisp dialect it's probably got some redeeming feature
