Question, How can I improve this? should I include strings? I'm tasked for my assignment to find the amount of profit made after selling the stocks.

My main question is, When I run what I have here, I want to be able to continue the sentence after "stockValue" variable on line 24.

What would be the best way to do that?

This is why college sucks for programming.
They spent too long teaching you to write dumb command line calculators.
They don't even teach you about stdin so you end up making stupid assumptions like getc() is for keeping the window open after you're done.

A functor (in the context of Haskell, not category theory) is a type constructor (like a generic) providing a function called fmap

A functor lets you lift a regular function (a -> b) into a function on your data type (F a -> F b)
Effectively it replaces all the a's with b's, using a function from a to b
For a container, that will apply the function to all the values.
fmap (+3) [1,2,3] = [4, 5, 6]
-- this is also called <$>
(*7) <$> [3,6,9] = [21, 42, 63]

An applicative is similar, except it knows how to take a datatype containing functions, and combine it with a datatype containing inputs (into a datatype containing results), i.e. F (a -> b) -> F a -> F b
For instance, a ZipList will take a list of functions [(+1), (*2), (/3)] and a list of inputs [3, 7, 1] and apply each input to the respective function
ZipList [(+1), (*2), (/3)] <*> ZipList [3, 4, 5] = ZipList [4, 8, 5/3]
The reason there's a ZipList is because the regular list doesn't do this - the regular list produces all combinations (applies each function to every element, and concatenates the results)

[(+1), (*2), (/3)] <*> [3,4,5] = [3+1,3*2,3/3] ++ [4+1,4*2,4/3] ++ [5+1,5*2,5/3] = [4,6,1,5,8,4/3,6,10,5/3]

It also knows how to put a regular value into the datatype (called "pure")
There are some laws for this that are important in some circumstances, but you don't normally need to know them
For lists, this just gives back a singleton list, pure x = [x]
For ZipLists this gives back an infinite list, pure x = [x,x...]

>>56590895
I really don't know... I guess I don't like having too much negative space on my screen, that and I know that Gohu has two variants (8pt and 11 pt), and I chose the higher one out of a whim

what do you think about making a "programming for dummies" visual language for my senior honors project? doable in 2 semesters?

>>56590847
The screenshot you linked is about Objective-C, not C#, and the question makes no sense for C# (where ints/chars are not implicitly castable to bools)

>>56590762
Monoids are extremely simple.
It's a datatype, with an associative binary operation and an identity type.
Basically, you can combine elements and there's some "empty" element

Binary: a <> b = r

Associative: a <> (b <> c) = (a <> b) <> c
(The parentheses don't matter)

Identity: i <> a = a, a <> i = a

>>56590952
Just write a bunch of #define macros in C and hide them under dummies.h or whatever.
You'll finish your dumb "language" in 20 minutes.

I actually understood this. Thanks. Now when I meme, I can do so with authority.

>>56590953
Wait... (And I fully acknowledge this is full-retard territory) I thought Objective-C and C# were the same thing. I've frequently seen them concurrently in StackOverflow, but that might be me not knowing the difference

Afraid not, chief.

>>56590988
Objective-C and C# are completely different languages (besides both inheriting a lot of syntax and datatype conventions from C).

GADTs/generalised algebraic data types

you've got algebraic data types:

data MyPair a = MkPair a a 

on the left is the name of the type (MyPair), the type variables / parameters (a)
on the right are the constructors (MkPair)
the things following a constructor are the parameters to the constructor, "a" is the type variable from earlier, so this

data MyPair a = MkPair a a

translates to this

template <typename a>
struct MyPair {
   MyPair(a, a);
   a p1,p2;
}

(if the name of the type occurs on the right side, then it's either recursive (for a parameter to the constructor), or the constructor itself is given the same name as the type, e.g.

data MyPair a = MyPair a a

)

Multiple constructors:

data MyCases a = Left' a | Right' a

The constructors are all 1 to 1 - all the information in them is preserved.
A different constructor is a different value of the datatype, e.g.

data Bool = True | False

(these constructors take no parameters)

There is a direct translation of ADTs into an OOP style - each constructor becomes a subtype
--

GADTs adds to this, you can now specify the signature of the constructors:

data MyPair a where
  MkPair :: a -> a -> MyPair a
-- MkPair takes an "a", and another "a", and gives back a "MyPair a"
-- the result must always be a MyPair something

but you can also specialise

data MyPair a where
  MkPair :: a -> a -> MyPair a
  MySpecialPair :: MyPair ()

-- (MyPair a)'s in general are now relatively untouched, but (MyPair ()) has an extra value (MySpecialPair)

If you were creating something like an expression tree, you could for instance require that the first parameter to an "if" branch will produce a boolean result

>>56591139
>A different constructor is a different value of the datatype
Sorry, a different constructor makes a different value
So even if they all take the same parameters, because they're different constructors they make different values.
Or if they take no parameters (like for Bool), then they just are different values.

I'm trying to think how I would implement this without trashing the nice modular design I have going.
Spoiler tags are easy, but code tags now means I have to bypass the whitespace filter somehow.

Maybe if I copy all text between

 tags into a separate buffer, overwrite the text with "AAAAA" so the whitespace filter doesn't touch it, and then memcpy it back.

CSS allows you to add scrollbars on overly long divs, right?

>>56591387
With GADTs you can then pattern match on each constructor, bringing any relevant details into scope (normally this just means the values they were constructed with)

data MyPair a = MkPair a a

func (MyPair x y) = x + y


data List a = Null | Cons a (List a)
-- a list is either empty or cons (a head and a tail)

len Null = 0
len (Cons _ t) = 1 + len t

-- _ is a wildcard that basically means that I don't need that particular variable, I could have just said (Cons h t) and not used h

The next thing to learn about Haskell I suppose would be type classes

>>56590977
If you understood that, then you're 80% of the way to Monads.

A Monad is an Applicative functor with one more operation

join :: F (F a) -> F a

.

That's it. That's literally all there is to them. The only other thing is that all these functions have to obey certain rules when you combine them in certain ways.

Here are the instances:

instance Functor [] where
  fmap = map
instance Applicative [] where
  pure x = [x]
  fs <*> xs = [ f x | f <- fs, x <- xs ]
instance Monad [] where
  join = concat

instance Functor ZipList where
  fmap f (ZipList xs) = ZipList (map f xs)
instance Applicative ZipList where
  pure x = ZipList (repeat x)
  ZipList fs <*> ZipList xs = ZipList (zipWith ($) fs xs)
-- ZipList is not a Monad, because there's no way 
-- to define join that satisfies the Monad laws.

The bind (>>=) operation is just another way to formulate Monads. You can define bind and join in terms of each other.

x >>= k = join (fmap k x)
join xss = xss >>= id

hello dpt.

not really actual programming, but using select case, instead of for individual users, how do i set it to a security group instead?

Case "barney.fiddledicks","raynard.goldsteinn"
WshNetwork.MapNetworkDrive "J:", "\\server\control point$"
End Select

for individual users, how to do it for a group? Is it just wshnetwork.*groupnamehere*?

as a programmer, I'm eternal noob, and while this project wasn't that big, it still took me a lot of time...
I did open-source it, partly at least (as a library). it's a website that went live a year ago, and got no regular users.
after open-sourcing the lib, someone asked me for a CLI tool... but, since I'm lazy, I didn't make it. I should, though, perhaps that way it would actually help someone.

>>56592292

If it's open source, they can make it. Tell them to stop being lazy.

I want strstr() to return the pointer location of the last occurance of a certain string.

Is it stupid to reverse the haystack and needle and then do something like

char *end = strstr(strrev(string), strrev(tag[1]));
last_occur = &str[len] - end;

last_occur becomes valid as soon as I reverse the haystack string again.

>>56592304
That philosophy only flies when you already have a sufficiently large install base such that users who are turned off to the concept bring no added value (ie. they likely wouldn't have contributed regardless of your response). When you have such a small project that you qualify "used by people" with "10+", the value of getting an additional person using your tools so as to spread word-of-mouth likely outweighs the burden of developing whatever it is they wanted (assuming their request is something reasonable, like a CLI wrapper for methods in the library or something so they can use it immediately, which is what I assume GP meant). Plus, your project starts to build a reputation of being open to suggestions, which makes it more likely the person you gained as a user will recommend your work to others in the future.

>>56592304
I mean, I myself could make lots of multiplatform desktop/phone apps with this lib... but the fact that my website had no regular users really dissapointed me. perhaps I'm a terrible marketer, perhaps the website is just shit, but, as a concept, it could be helpful in other context... perhaps barely anyone cares about this tool

A way you could do this without modifying the input would be to continuously use strstr until there is nothing left.

#include <stdio.h>
#include <string.h>

char *strrstr(const char *haystack, const char *needle)
{
    char *match, *prev = NULL;

    while ((match = strstr(haystack, needle)) != NULL) {
        prev = match;
        haystack = match + 1;
    }

    return prev;
}

int main()
{
    const char *str = "testtesttest";

    printf("%s\n", strstr(str, "test"));
    printf("%s\n", strrstr(str, "test"));
    printf("%p\n", strrstr(str, "abcd"));
}

I think this is pretty shitty for the worst case though.

Terrible naming conventions. I should be able to generally know what a method does, and what the contents of a variable are, from just the name. I shouldn't need to read the function definition to learn that "ftcc" converts degrees farenheit to celsius.

In C, void pointers are automatically converted to other pointers. There is absolutely no reason to cast and all it does is repeat information.

A lot of your comments are explaining 'what' you're doing. You can clearly see that from the code itself. These kinds of comments are pointless.
Comments should explain 'why' you're doing something and give a much more high-level explanation of what's going on.

Basic Mathematics by Serge Lang

Buy/Pirate this book (he's dead). It's highschool math, from the perspective of a Mathematician. You will learn up Pre-Calculus and be prepared for rigorous proofs later.

An Introduction to Mathematical Reasoning" by Peter J Eccels

This changes you from rote drilling and being a human calculator in highschool to learning what math actually is, and what proofs do. Excellent, excellent book.

How to Solve It by G. Polya

How to do proofs, written in 1940s and still for sale in every Chapters/B&N bookstore to this day because it's the best proof helper that exists.

>>56593373
just use linux m8

>>56593450
I also recommend lang and polya.
Though how to solve it didn't really go into proofs, just heuristic, which is important for proofs, but there's also a book called "how to prove it" which centers around proofs.

it just 'is' bad practice and against readability, just like capitalizing variable or def names or not indenting

You will hopefully never see it in another programmer's code

only capitalize class names too, your variables can be named like celciusToFahrenheit or celcius_to_fahrenheit based on your preference but CelciusToFahrenheit is considered bad form (and no one else uses it if you look at the other snippets in this thread)

I'm thinking if I write a couple of cheap Bash scripts, I may be able to skirt around this tool without having to flash a ROM that doesn't have root baked into the damn thing. Just move su to somewhere on /storage/sdcard/0 temporarily when I want to use Pokemon Go, and copy it back to /system/bin and /system/xbin when not in use!

(and here I thought I might not get a chance to need a bash script on my phone)

It really lacks functionality at the moment (saving changed seems somewhat important). In the case that I won't get bored of it, it might get better than hexedit (I can't believe you can't move with the home-row keys in hexedit, seems like a waste).

>what language?

Don't have an online repo. This is my first ncurses project and it's messy. As I learn more and more of how to use the library I might have to drastically restructure my program. At the end I might upload it somewhere if I'm pleased with the code quality.

>>56595235

>>56595235
why do you have to declare that cuck is an integer?

What's the best way to get really good at programming (mainly C++). Obviously the answer is to program more but I wanna know more specifically

Is there a list of projects I should try out. Maybe a site with challenges or something?

>>56595504
short answer: yes
long answer: no, because compilers linking objects together just know the function name, type, and arguments and can't optimize functions calls completely compared to compiling all the source files together

realistic answer: it doesn't matter, just do whatever is best for the project (objects can prevent unchanged files from being recompiled which could speed on compile times on big big projects)

>ask any lawyer
Any decent lawyer should complain about the political process of writing laws rather than the language. A law is usually determined by 'intent' so you make some historical judgement.

But why not codify that? Why not have the person write down the intent (such as moral motivation for the law) along with the law to make it perfectly fucking clear what they mean and have that be part of law? Then every case could be judged based on the law alone rather than how its been used in practice which is just as arbitrary you're just going by a second hand source that doesn't know what the fuck they're on about.

English is very verbose though.

>>56595913
>>56595942
>>56595954
Doesn't c# have some build-in hash-table magic when using switch with a string or something?
At least that's what I heard.

Let's say that you have the following C++ classes:

class A {...} 
class B {...} 
class C : B {...}
class D : B {...}

class E : A {...}

C and D both contain a pointer to A. Now, I want to create an instance of both C and D in A.

If I declare these classes in the header as B*, and simply let the .cpp file create the C and D objects, I avoid the nasty circular dependencies which I couldn't solve even with forward declarations. However, when I try to access the members of A from its subclass E, this->a recognizes a as B* and not C*/D* and thus won't compile when trying to access the subclasses' methods.

What I'm wondering is
1) Is it the correct thing to do, to define the member variables as a base class pointer?
2) How do I access the methods of C and D from E?

>What arbitrary constraint does C# put on C's most prominent abstraction for jump statements that disallows such convenient use?

>>56595994
There's a threshold somewhere around 6-10 entries that makes the behavior either a sequential IF (small quantity of entries), or a HashTable (if it's predicted to be more efficient).

Obviously, the overhead of generating the hash table is not efficient for a tiny amount of cases.

I started playing around with haskell 30 min ago, its not bad at all. It took a bit of work to setup vim properly and add all build commands but it works nice and i get types on the fly. I actually like it and cabal is pretty nice.

>>56596037
I can understand why this could cause problems for unobservant programmers, but it is a bit silly that fall-through isn't supported.

From a performance standpoint, wouldn't that force the potentially generated hash table to be sequential, and thus force an additional sort?

The machine would have to know not only the associations between case and action, but also between subsequent cases.

Why do people still write Batch scripts when Powershell exists?

>>56596204
Because powershell is
1: non-standard (not sh compatible)
2: nobody uses it
3: it was not free software
4: it is a pain to compile
5: .net lol

>>56596180

What? Hash tables are inherently unordered.

Nigga, your dick was like a centimeter long at one point, but I don't think anyone brings that up.

>>56596268
>>it was not free software
>>judging a technology on its previous form
I am not judging anything, I am simply saying why people do not prefer it.

>>56596256
Well, I know, but the point is that if you allow fall-through like that, you have to store the values in a sequential data type with lookup, assuming there are enough switches.

>>56594740
I don't think you need Prolog. Haskell's Logic monad is as easy to use as Prolog.

>>56596301
Did you mistype or something? In your post you say it's silly that fallthrough *isn't* supported, because it forces it to be sequential.

Also it doesn't have to be stored sequentially, you just need a jump at the end of one block to the beginning of the next. I don't know how it's implemented in C# though, you could take a look at the IL if you're curious.

>>56596016
>C and D both contain a pointer to A. Now, I want to create an instance of both C and D in A.
No, they do not. They contain an instance of A, which contains an instance of D which contains and instance of A which contains an instance of D and so on. Which doesn't compile for obvious reasons.
>Now I want to create an instance of both C and D in A
You're never gonna have that work if you're inheriting.
You're forcing yourself to deal with the woes of OOP though. So OOP is very poorly suited to this (just like any task really but more so here than anywhere else).
Also you should phrase it as
"C and D both contain a pointer to the type A".
The other way of phrasing it would imply you've instantiated objects with the identifiers C, D and A.
>if I declare these classes in the header as B*
Well that's not doing what you did before. There's no circular dependency because B doesn't inherit A, C & D doesn't either.

>1) Is it the correct thing to do, to define the member variables as a base class pointer?
It all depends on what you wish to achiveve.
The idea of inheritance in OOP is often to spare you redefining methods for subclasses. So if A has a foo() function you don't have to write that again for C or D. C and D contain all the members of A so foo() can work on C or D aswell as A.
>How do i access the methods of C and D from E
Well you can't. Draw this up as a tree and see that they're all entirely seperate.

I think you need to understand Object programming better. It's a horrible paradigm, but I'm assuming you're in school and have to learn this stuff.

Is a rather short introduction to OOP which can be helpful. After 26:00 it no longer applies to C++.

GAS ALL THE HASKELL TRANSVESTITES.

>>56596016
>>56596372
Oh and to make things a bit clearer. Your code example gives you:
A can call the methods of A.
B can call the methods of B.
C and call the methods of C and B
D and call the methods of D and B
E and call the methods of E and A
You only have a single step of inheritance here.
If you wanted deeper inheritance you could write.

class A {...} 
class B : A {...} 
class C : B {...}  

For instance.
Now:
A can call the methods of A.
B can call the methods of A & B.
C can call the methods of A & B & C.

C contains all the members of B and its own members.
B contains all the members of A and its own members
A contains its own members.

This is all basic stuff but i'm just putting it out there because you don't seem to know wtf you're doing desu.

>>56596429
>C contains all the members of B and its own members.
Oh and to be clear.
This means that C contains the members of A too. Since B contains the members of A.

>>56596230

>non-standard
It is just as standard on Windows as Batch is. Moreover, Batch is not sh compatible either -- not by a long shot.

>nobody uses it
Nobody in their right mind uses Batch. Most Windows system administrators use Powershell. Yet these days, I still see newfags writing .bat files for non-trivial programs.

>it was not free software
cmd.exe is still not free software. There's a free implementation, but nobody uses it on Window.

>it is a pain to compile
Powershell is not a compiled language.

>.net lol
.NET is part of what makes Powershell good. Rather than relying on external programs, you can take advantage of the standard library to get a lot of your string and array processing done out of the box. Moreover, if your script needs to do anything convoluted, you can easily just load a DLL compiled in C# or F# for things like, oh I don't know, graphics.

>>56590803
Language?

And I did not say that it is. I said that Powershell by itself is a pain to compile.

Anyhow, there is no such thing as a "compiled language".

Guys how do I learn assembly

>>56596500
depends on what you define as "compiled" and "language"

I made a shitty script program in Java, and now I'm trying to make it's GUI with Swing.
I want to run a method A (which scans a website and puts some data in a json file), and show some strings (generated by A) in a panel while A is running.
I can achieve this by keep sending the strings to the panel and revalidate and repaint it. This doesn't sound like a good approach.

I think running two threads at the same time would be better, thread1 runs the method A and thread2 clears the panel and retrieves the strings and puts them in the panel, every second or so.

Is there a better way to do this?

>>56596515

No joke it's pretty good and does really start from the start.

>>56596548
Have a place where you place the strings, seperate from the GUI entirely.
Have thread 1 update it. Have thread 2 draw the GUI based on that information.

You don't really have to worry about thread syncing because the GUI doesn't modify the data. You can just let it all run asynchronously.

It's a good idea to keep your code that actually does stuff away from the GUI. And that's a fairly good way of doing it.

>>56596490

That would explain it. Honestly, I would see no problem with people writing Bash scripts more on Windows, but if one does not wish to use Bash for whatever reason, one should at the very least use Powershell instead of Batch. Batch is a god-awful language that should absolutely not be used anymore except when maintaining really, REALLY legacy systems where no better alternatives exist.

>>56596500

>I said that Powershell by itself is a pain to compile

Oh. As in it's a bitch to build? I will agree with that sentiment... and in fact, that all of the CoreCLR is a pain in the ass to build, and to integrate into anything. I'm particularly not a fan of Microsoft's current setup with the "dotnet" build utilities that rely on a project.json file and all that. I'd honestly just like corerun and csc installed to somewhere in my $PATH (like Microsoft currently does with Powershell), and to be allowed to use my own choice of build systems.

Can someone recommend an editor where I won't have to use my fucking mouse where I can let the code flow freely from the keyboard without distractions?

Batch should have never existed in the first place, honestly. It has done more harm than good.

If batch was at least half good or had any feature at all that was missing from sh I would understand. However it does not, it's literally shit.
Any experienced programmer could make something much better than batch in half a day.

Just because there are an infinite number of valid C++ programs that cannot be compiled does not mean that the vast majority of valid C++ programs that will ever be made by humans are not able to be compiled.

1. Backwards compatibility, ability to be used as a systems language.
2. Both are webshit. Both have an == operator so horrible that === must be used. Both are dynamically, weakly typed languages.
3. They're just methods on objects. They can also be overridden.
4. C# can switch on strings. C can't.
5. Fuck if I know.

>>56597338

C can switch on strings.

It just looks like a series of else if statements.

>>56597469

I will agree that C is a great language. I am merely pointing out that when you are comparing language features between C# and C, one of the major differences between their switch statements is that C cannot use its switch statement with strings, where C# can. Please learn reading comprehension sometime in the near future.
