apariciones works fine

Do not count the 1st element or the element that matches the array size. Not all functions will accept the first element of an array. Also, the element that matches the array size does not exist. It is outside the size of the array.

please a need help

Here, you have defined memory inside the function, and somewhere else you have to release it, which can icrease the possibility of error if the programer forgets that. It is a good habit to define and release the memory in the same place. You could feed the resptr as the second argument to the function: int bhmac(char *data, char **resptr) { char *res = 0; res=(char*)malloc(...); if (!res) return 1; // error in allocation *resptr = res; .. return 0; } And in the place you call this function: char *resptr = 0; if (bhmac(data, &resptr)) return 1; // error ... if (resptr) free(resptr); resptr = 0;

You return a pointer to local array ehich is deestroyed right after function returns

but what is the problem? I create in any function exec a new array ... it is a for and I am creating a new array everytime

If the method POW in the STL returns a CONSTEXPR. Why can I do it? int a =0; cin >> a; a = pow(a,2); In theory if something is CONSTEXPR should be now during the compilation time.

Hai everyone.. I'm getting implicit declaration of function strrev when I used strrev() function. I also copied a program on the function and I run it. But no use. Anyone please help me..

don't read shit books written by shit authors like Yashwant Kanetkar

I didn't understand bro

oh. i thought you were asking the question from Let Us C by Yashwant Kanetkar

Let us C is recommended by many people 😅

As second argument, i need to pass a pointer to pointer

it's a good filter. you get to immediately know whose advice should never be followed for any topic

nice

hello there! can anyone share source of information about required skills for game development?

about gave development? you mean low level or something high level?

low level

know pipeline (opengl/directx)

where’s Vulkan

I think that person might not even know what you're talking about

I think that person might not even know what you're talking about

know how gpu works, maths for matrix and vectors

i just don't know difference between opengl and Vulkan everything else obviously

thx a lot

I think that person might not even know what you're talking about

do you have some background?

web, python

You can also learn more higher-level libraries for graphics, like SDL or SFML (I'm using this last one quite often nowadays), but don't expect your game to be really that efficient

web, python

(or even higher GML/Unity/Godot)

That works if you have an idea and want to implement it as fast as possible, but I haven't really learnt a lot using those

if you want to just get into game development you could try pygame

bruh python

it's like the language i know the most Dimka
