Why can't we treat CPU like we do with GPU and have drivers for it?

To the guy in the last thread- you recommended the book "How to Design Programs". I'm looking at it on amazon right now, is 22 bucks a decent price for it (used)? Also, I see it was written quite a few years ago, is the information still accurate?

Thinking of making some sort of 4chan desktop browser app (similar to clover, but desktop only, like the "messenger" standalone app). Would this be similar to building a small-scale browser? And more importantly, how should I go about learning how to implement certain features?

>>58816690
>>58816707
Alright, I've got it working. Here's my code.

#include "R:\C++\std_lib_facilities.h"

int main()
{
    cout << "Input some numbers.  When you're done, type a letter followed by Enter: \n";

    vector<double> distance; // initialized vector dist to 0
    
    double dist = 0;
    for (double dist; cin >> dist; )   // for loop, when numbers are input, store them in dist
        distance.push_back(dist); // take the dist numbers and put them at the end of our vector

    double sum = 0; // initialize a way to add values of dist together
    for (double x : distance) sum += x;
    
    sort(distance); // sort ths dists so it'll be in numerical order so I can output the smallest and largest (this seems janked)

    cout << "The smallest distance is: " << distance[0] << endl; // print the smallest distance
    cout << "The largest distance is: " << distance[distance.size()-1] << endl; // print the smallest distance
    cout << "The sum of all inputs is: " << sum << endl;
    cout << "The average of all inputs is: " << sum / distance.size() << endl;
}

Let me know what you all think/where I can improve. As far as getting the sum of the inputs to work, I found the line "for (double x : distance) sum += x;" a few pages back in the book, but he doesn't really exactly explain what's going on there. I assume the 'x' just stands for 'whatever is input'?

It's actually Windows 8.1 I'm running. For old games, it would be wise to set up a VM. I have one that runs x86 XP for Baldur's Gate and the like.

C++ is a horrible language. It's made more horrible by the fact that a lot of substandard programmers use it, to the point where it's much much easier to generate total and utter crap with it. Quite frankly, even if the choice of C were to do *nothing* but keep the C++ programmers out, that in itself would be a huge reason to use C.

In other words: the choice of C is the only sane choice. I know Miles Bader jokingly said "to piss you off", but it's actually true. I've come to the conclusion that any programmer that would prefer the project to be in C++ over C is likely a programmer that I really *would* prefer to piss
off, so that he doesn't come and screw up any project I'm involved with.

C++ leads to really really bad design choices. You invariably start using the "nice" library features of the language like STL and Boost and other total and utter crap, that may "help" you program, but causes:

>infinite amounts of pain when they don't work (and anybody who tells me that STL and especially Boost are stable and portable is just so full of BS that it's not even funny)
>inefficient abstracted programming models where two years down the road you notice that some abstraction wasn't very efficient, but now all your code depends on all the nice object models around it, and you cannot fix it without rewriting your app.

In other words, the only way to do good, efficient, and system-level and portable C++ ends up to limit yourself to all the things that are basically available in C. And limiting your project to C means that people don't screw that up, and also means that you get a lot of programmers that do actually understand low-level issues and don't screw things up with any idiotic "object model" crap.

So I'm sorry, but for something like git, where efficiency was a primary objective, the "advantages" of C++ is just a huge mistake. The fact that we also piss off people who cannot see that is just a big additional advantage.

But I'm sure you'd like it more than git

>>58817486

Overloading (ad hoc polymorphism) is fine, the problem is when it's mixed with implicit conversion.

>>58817879
Precise -> Less precise
Write the function once, have it return a float and take floats, and cast the result to an int as necessary (and the parameters to float as necessary)

int x = (int)func( (float)intvar1, (float)intvar2 );
float y = func( floatvar1, floatvar2);

No, we're discussing how + totally only has one type and everything else is just casting.

You know, how it's a myth that + actually works on integers, floats and doubles differently, generating different machine code, and how + is actually just a purely monomorphic function that only works on 1 type that everything else is just cast to. (and presumably back from)

Nice pasta, but Ada mixed with C (because some autist gives it hard to use pascal-like syntax) is the unironically the only sane choice.

>>58817902
overloading and ad hoc polymorphism aren't the same things at all
implicit conversion is like overloading but automatic for types that have implicit conversions.
check out how C++ does it. in some ways it's shitty because you can't easily reason about the code. in other ways it's really nice because it lets you implement a lot of things that are usually hard wired to the compiler in other languages (e.g. string literals, move and copy semantics). also lets you "disguise" types with other types which could possibly be useful for extending functionality without changing older codebases

>>58817945
>overloading and ad hoc polymorphism aren't the same things at all
>In programming languages, ad hoc polymorphism is a kind of polymorphism in which polymorphic functions can be applied to arguments of different types, because a polymorphic function can denote a number of distinct and potentially heterogeneous implementations depending on the type of argument(s) to which it is applied.

You can develop applications in C just as quickly as in Java and with similar levels of correctness. I understand you probably haven't had a real job yet, or even completed the first half of your degree, but there are a host of tools around C that make working with it very easy.

Writing Tests for C is also a lot easier to do than with most scripting languages and you can turn them on or off with a flag in your makefile.

C also has a gigantic fuckload of libraries meaning you almost never have to do anything but glue libraries together when making "modern" software.

I'm sorry you can't figure out how to use libraries. Maybe try reading a book?

Why do other programming languages even exist when all you need is the God of all programming languages Java?

how do people ever do projects as a beginner or intermediate

If a beginner or intermediate can realistically do the project then it's either already been down 10 times better (in which case it's not exciting), or the problem is trivial (in which case it's not exciting)

What fucking beginner book are you reading? No one does #include with an absolute path. It makes your code completely non-portable, even between computers with the same operating system.

>>58818144
Haskell is actually a good language which can produce quite efficient code if used correctly while maintaining a high abstraction from the machine. One thing it does better than C is parallel processing as all you need to do is turn on the compiler flag and it will workout where it can (you can even force it) unlike C where you must write several lines to do the same.

>>58818176
it is and is mainly used for comparing how other languages handle such a simple task

Guess programming isn't your thing, I've stayed up long nights and lost much sleep working on writing trivial programs for no reason, I think it's really fun

>>58818222

Anon, there's making a program that only builds on one operating system, and then there's making a program that only builds on one fucking computer. You should, at bare minimum, use a path relative to the source file, or relative to your compiler's search path for headers. Otherwise... okay, imagine you're working with a few coworkers on a project. I'll play devil's advocate here and say you're both using Visual Studio and Windows 10, and that you only really expect the program to target Windows 10. You submit a patch to your Git repo (or whatever VCS you use), and your coworker downloads it to add his own. You both have the same operating system with the same updates, and the same version of Visual Studio. When your coworker tries to build, however, he runs into a problem. His filesystem doesn't look the same as yours. In fact, he doesn't even have an R:\ drive. He just has a C:\ drive. Now he has to structure his filesystem to look identical to yours, when the program should be self contained on its own, so that regardless of where it is cloned into, and regardless of what the rest of the filesytem looks like, it should build regardless.

You're going to make life hell for your coworkers in the future, Anon. Take my advice: your book is bunk.

>>58818302
i dont mind practically trivial but conceptually nontrivial problems (essentially, most math problems)

unfortunately that doesn't help with large projects

>>58818310
I'd recommend implementing big stuff that is already "done" if you want to learn and get some good practice...

Write a super shitty web-browser. Write a web server(much easier). Write a database or a compiler, etc.

>>58818310
I think you need to learn about design patterns for medium to large programs is your issue

>>58818222
You will when your program leaves your computer

>>58818327
>compiler
That's one of those things where it's not something that's "been done", because you can compile whatever the fuck you want to, including a new programming language.
Writing a good compiler is pretty difficult, though.

>>58818329
>design patterns
I really hope you're not talking about """""design patterns""""".

>>58818340
you need to learn to shut off the part of your brain that thinks it is trivial and just do it and write those small projects and work your way up

>>58818329
i think you're right. i'm also trying to read through moderately sized codebases of interesting projects

>>58818327
yeah maybe but the knowledge that it's been done and my attempt will be shitty and offer nothing new isn't fun

>>58818353
I'm not the original anon you were taking to. I was just throwing in my opinion.
But yes, that anon needs to stop worrying about the scope of his projects and just do something.

>>58818257
well for a beginner a tool such as that would be difficult since they need to learn how parsing works. If it's in C then sprintf, fprintf, ect... but I see what you mean. Guess they could always go for a game engine as it's on the list for being one of the most complex projects to work on if OpenGL, OpenAl, Vulkan, ect... are involved.

>>58818259
The syntax is considerably simpler than C. Quite a large part of the syntax is actually just normal functions written to simplify the code. Speed depends on what your backend target is (llvm is getting there iirc) and how you write the code as sometimes it can generate code equivalent to the fastest possible implementation in C.

>>58818310
you need to stop thinking so much about it and start the first project that comes to mind.

>>58818367
>The syntax is considerably simpler than C
No anon, I think you mean considerably "different" than C.
Haskell syntax is not "simple".

Never heard anything more wrong

>>58818357
Would suggest thinking forth and SICP

>>58818385
it is when you realise most of the code is actually just functions which allow you to "pipe" output from one function to the input of another and the use of anonymous functions makes design a lot easier.

iirc this is most of the syntax
<id> :: <type>
<id> = <expr>
let <id> = <expr> in <expr>
data <id> = <id/symbol> <optional type> | ...
type <id> = <type>
and the rest is sugar

>>58818436
Please why haskell syntax is more simple than C syntax.
Function calls, function signatures, list comprehensions, pattern matching, typeclasses, $, and so on.
I think you're probably confusing referential transparency with simple syntax.

Even then, it would help if you actually defined what you mean by simple.

>>58818476
>and the rest is sugar
And is still part of the syntax, and is not exempt from discussion/criticism.

>>58818396
read suckless, ffmpeg, openbsd, any clean codebase you can find.

Also thinking-forth will prepare you for larger projects in any language from just the first few chapters as it covers nearly every part of design you want to know.

is there a c++ alternative to winforms or is this where i give up? should i use SFML or SDL? i need some buttons, some text input and a square to display data.

>>58818488
$ isn't syntax, it's an operator defined in the standard library

You can't just rattle off stuff like that and think it immediately makes it complicated.
Every single operator in C is its own syntax, nevermind literals, arrays, (for types) pointers, function pointers, arrays, macros, etc

Every Haskell operator is a library function, with the exception of tuple operators (e.g. (,)) and (:) (which doesn't need to be special syntax)

C also has function calls, except to pass multiple arguments you give a list ( .., .., .. ) so this also cancels out Haskell's tuple syntax, as well as its function application

Type classes aren't a great deal of syntax -
instance _ where

Signatures don't have much syntax either.
:: -> and =>

>>58818530
well there's GHC if you like haskell, chicken scheme if you have an interest for a lisp, and... running out of things here...

Most will be C as it's the most widely used language but you can find projects in other languages that are good. I mostly deal with C, Forth, Scheme, and Haskell so projects related to them are the only ones I can recommend.

The book is great as it covers how to design your data structures to solve tasks without needing much code at all (look at the roman numerals solution) and you can go off making your own games in just a few lines, maybe get forth running on an arduino and start EE related projects with it.

>>58818589
>and (:) (which doesn't need to be special syntax)
and I also wish it wasn't

plus if TypeInType and GADTs ever get standardised, I hope they make tuples a library feature too.

What does overloading an insertion operator do in C++? Does it make it so you can cout objects that aren't accessible in that particular function? I'm confused about the purpose of this feature.

>>58818923
>insertion operator
What?

Case 1. Java programmers learn C++. People expect this to be hard, and it is actually hard.

Case 2. C++ programmers learn Java. People expect this to be easy, and it is actually easy.

Case 3. Java programmers learn Rust. People expect this to be hard, and it is actually hard.

Case 4. C++ programmers learn Rust. For some reasons, people expect this to be easy, but it is actually hard. In my experience, it is equally hard for C++ programmers to learn Rust as for Java programmers to learn Rust.

>>58818877
all the more reason to go faster

>>58818929
can i borrow this argument for the next computer club debate

>>58818923
Operators themselves have no real properties (except order of operations)
You can make >> and << do whatever you want
In fact, in regular C (and for most C++ types), they're bit shift operators, nothing to do with streams.

You could use an overload of << that has a std::ostream& on the left to cout.
You could also call the function "print".

Though there are more women than men that use the name Ruby, it is gender neutral, and in fact, was once a common nickname for men named Reuben. Moreover, I first started using this name in a /vp/ thread roleplaying as one of the male protagonists from the Pokemon manga. I continued using it on /g/ due to my preference for the programming language of the same name.

Do not be misled -- I have stated on countless occasions that I am a man.

>>58819293

Rust is an acceptable systems language. Although strictly speaking, I have met someone recently who was able to use a Prolog program to find a bug in Rust's type system. That is, not the compiler per se, but the specification of the language itself. Apparently they never formally proved the type system to be correct.

Working java.

Say I need to call some methods in no particular order, but would like to randomize the order I call them in each time, how could I go about doing this?

My current idea is to make a List of method calls, something like this:
List<> methodsTo Call = new List<>();
List.add(method1()).
List.add(method2())
List.add(method3()).

Now we just shuffle the list, and iterate through:
Collections.shuffle(methodsToCall)

and voila:
For meth in methodsToCall:
execute the method here?


Only problem is the above approach isnt really supported by the language. There must be a way to get this to work without dealing with generic types or interfaces, making all the methods in their own objects or something silly like that.


Tl;dr can anyone find a way to randomize the order of executing some methods?

I'm not a girl.

>>58820465
If you're not a girl, then why do you have my little pony dolls?

>Actually advocating for C++
Kill yourself, my man.

$ is just a function. And that's a pretty exhaustive list of syntax elements.
