i'm currently working through the official C++ tutorials, does anyone have any tips or resources for game development in C++?

Yeah, I agree, but probably for the exact opposite reason as you. C is useless for writing anything other than FizzBuzz, 99 bottles, and Hello World. Haskell is useless for anything other than re-implementing the mathematics field's favorite functions which already exist in other languages, then jerking your ego off about how you did it the "correct" "clean" Haskell way.

Good alternatives to Haskell : Ocaml, Clojure, most other functional languages.

Good alternatives to C : Anything that people ever consider "an alternative to C" is usually significantly better than C as well. Fortran, LLVM IR, etc.

If my husband borrows my clothes, will he really become a better programmer? He keeps asking me to let him.

Java is and always will be the best statically typed language in existence.

If you first put that excuse for a language (I'm looking at you Rust) away

enable_if needs a specific type name to instantiate, since it defaults to void.

>>60146558

>>60146575
Yes, Haskell can be compiled to C, and there are macros and other things you can use to do inline C.

In not thinking about my winform order I created a main menu and character window after I already made the world. The mainForm design is always the first screen when the program runs and I'd like to change that. I figured it would work by hiding the mainform on its class and showing the menu on its but that's giving me an error at the mainform here

private MainMenu startmenu = new MainMenu();
        startmenu.Show();

I'm sure there is a simpler way to make a different form run first

They revolve around side effects. A function isn't pure if the same argument doesn't result in the same output every time. IO of any kind is impure.

You'd implement each entry as a struct, something like

};

And store a number of those structs in an array.

>>60146678
That's like saying C can't do I/O since you ultimately need to resort to asm to communicate with peripherals.

>>60146704
I seem to recall that linear congruential PRNGs use the previous result as the seed, for everything but the first call (which requires a seed to be generated externally). Which means you could implement as a pure function, if you require the caller to store and provide the result of the last call, rather than storing it internally as a local static variable in the callee.

>No, and as I said earlier, you could take a function that interprets an IO2 action (where IO2 is your custom IO), and put a function in between that ALTERS that io action (by which i mean returns it, altered, not mutates it).
A void function in C always evaluates to the same value, it's 100% pure.

No, a void function doesn't "evaluate to a value" at all. The "value of a function" in C is a compile-time abstraction, all it really means is helping the compiler figure out which mutable global variable (IMPURE! IMPURE!) to modify by the function.

I'm making a C# program with one thread for networking and another one for computing. First one waits for client command, sends that command to second thread, waits for result and sends it back to client.
However, first thread should still listen for new commands (in case client hits cancel) while waiting for the signal from the second thread. Whats the best way to do that in a single thread?

I thought about using receive with a timeout, then if client didn't send cancel check if the results ready, if not go back to receive.
First time in C# btw

>>60147306
>The "value of a function" in C is a compile-time abstraction, all it really means is helping the compiler figure out which mutable global variable (IMPURE! IMPURE!) to modify by the function.
Yes, like in any other language because guess what, that's the entire point of any program running on a computer.
Any language or compiler not emitting code modifying global state would have zero useful effects and might as well not be executed at all (in fact, couldn't be executed at all on a real computer since at the very least a global instruction pointer must be incremented to go to the next instruction).

spaces or no spaces after if/while/for

or

WriteLine("Subhuman.");

Java is the best programing language.

>>60147436
If you start at the beginning: yes

>>60147501
No spaces, and braces on the next god damn line.

>>60147501
neither of those are acceptable

>>60147501
First one is preferable, however that syntax is horrible. Either put the controlled statement on the same line, or leave it on the second line, but indent it, and surround it with braces.

>>60147436
arrays are generally faster due to cache locality.
linked lists may be spread all over memory.

>>60147516

I don't really get the space between while keyword and the parenthesis of the condition, whereas there are no spaces between function name and the parenthesis of the parameter list.

I also do this but I don't know why, is there an actual reason for/against this?

>>60147551

while(girth <= 6)
{
   WriteLine("Subhuman.");
}

The only acceptable way.

>>60147623
To distinguish between functions and built-in language constructs.

>>60147623
The reasoning is that while/if/for aren't functions, so you shouldn't treat them as such, though personally I leave out the space.

>>60147541
Im doing some research into this. My program has two types of dynamically allocated memory: audio data in files and connection pointers. I figure i can use system calls to put audio data in its own section of memory (have some max filesize parameter) and then have the connections be the last thing allocated by brk and sbrk so that they can be in sequential order at the end of the data. Terminated connections will be freed and if a new connection comes in it will either fill the hole of the old connection or be appended to the end of the heap. This way ive got a linked list in order and i can just use pointer arithmetic and headers instead of malloc abstractions etc

Generally speaking, is it true that OOP users have very low IQs?

So I've had this idea for a program but I'm not sure where to start. In terms of my background, I did some elementary java in university a few years ago, and learned some basics about C++ and python (I know, pretty normie tier).

So I want this program to take an audio file, and scan through the waveform to see where the music increases/decreases volume and then adjust the system volume accordingly (which would be set in the program) to maintain an optimal listening experience for times where keeping a certain volume is required (for example, it being night time and others being asleep, I would want to keep my music quiet but still audible to me). So for instance, if the music was very quiet, the system volume would turn up (gradually would be the best) and in loud parts it would turn down to some defined amount.

My biggest issue is I don't even know what language would be suitable to attempt this in.

>>60148051
isn't the only language with easier syntax ruby?

It's pretty neat though. It uses binocular vision to locate more distance objects, and sonar for short range collision avoidance. Then it does pathfinding through the object field, before converting it to motor output powers using feedback control. The JS communicates with an arduino over serial to send commands to the motor controllers. Also it does pose estimation between image recognition frames using wheel encoder data.

Daily reminder that these are shit:

weak-typing
Weak-typing only leads to constant headaches and exploits.

braceless enclosures
Braceless enclosures look fucking awful and are harder to see layout properly unless you use a decent IDE or 8-width tabbing/spacing.

OOP as a coding method. (note method)
OOP as a foundation for code is fucking atrocious. Doing everything in OOP is ridiculously high-overhead.
OOP has some useful features, but high-inheritance layers just reeks of retardedness. It's on a level as stupid as 20 IF chains when it 90% of the time it can be refactored in to a loop or recursion, or pure math.
OOP is way too easy to abuse. More so than GOTO used to be abused back in the day.

>I seem to recall that linear congruential PRNGs use the previous result as the seed, for everything but the first call (which requires a seed to be generated externally). Which means you could implement as a pure function, if you require the caller to store and provide the result of the last call, rather than storing it internally as a local static variable in the callee.

You'd then have a hashing function and you'd be forcing yourself to write impure code to use it as a PRNG, with a global variable and a side-effect outside of it.
