C Programming Tutorial # 33 - malloc() and free() - Dynamic Memory Allocation - Part 2 [HD]x

Ya. Seriously. We appreciate your help but you aren't a college professor and I don't want to pay like 20 or whatever dollars if I only need a vid here and there.

why dont you just use the sizeof operator?

@czarkefa80

Use sizeof() operator inside malloc. I.e. for: int array[1000] you can write: malloc(1000*sizeof(int)), thus allocating [(1000*4) = 4000] bytes of memory on heap (whatever heap is lol).

[czarkefa80]

@doubleja Haha thanks :). The heap is free memory that floats around, as opposed to the stack, which is a set of memory that is automatically allocated. We get what's called stack overflow. I hope this helps. Yours helped, so cheers.

Thanks for the tutorial you explained it really well!! I have a question though, how can i allocate memory for a matrix, lets say i recieve an integer N from command line how can i allocate memory of size N*N?

whr's the rest of the tutorial?
