Do you guys cast mallocs when writing strictly C, if yes - why? If no - why?
mov $22, %rax

yes, because if you don't you get a warning
mov $22, %rax
and that's a good practice

No, you don't have to cast the return value of malloc in C.
It does not yield any warning at all, even with -Wall -Wextra -Weverything -pedantic.
That casting practice is only for C++, not C.

Since it's a void pointer I always find it unnecessarily redundant, but at Uni they, teach us that it's a must without providing a good explanation

I think it is only a must if you code in C++. So if you want some part of your C code is portable to C++, then it is a good habit.

But why not? I think is a good practice for portability (by compilers point of view) and to be sure that everything works well... At least but not the last for readability

Gtk vs wxwidget?

You can reinvent gui building on sdl I didn't did that till now

We can build that in a few days not bad

Also you have a lot of chances for your software to become even messier

Cuz now it's your shitty code lmao

Since you speak Russian, I recommend you to watch C++ Lectures from Konstantin Vladimirov — they are really awesome
I think he will be my professor, if I'm not mistaken

I've heard he's really good

Excuse me, may i ask?, i have code
If(j==(i-2){
printf("%d",j);
Can i add if else again the i-2, to i-4, i-6, i-8, i-10, using for loops?
Thank you
Pavel

Yes, replace 2 with your loop counter (either multiplied by two, or increase it by two each step (k+=2 instead of ++k))
tartaerae

Is it?
If(j==i-(for (int k=0; k<=n; k+=2)))
Pavel
Is it?
If(j==i-(for (int k=0; k<=n; k+=2)))
the other way around, loop should be outside and if inside
Pavel
for () {
if () {
...
}
}

Can we ignore values in structured bindings as we do in std::tie with std::ignore?

There are some proposals about it with pattern matching

Nah, I don't think so
They plan it to C++23, C++26 top
