C++ creating arrays

Question

Why can\'t I do something like this:

int size = menu.size;
int list[size];

Is there anyway around this instead of using a vector? (arrays a

Answer 1

C++ does not allow variable length arrays. The size must be known at compile-time. So you can't do that.

You can either use vectors or new.

vector list;

or

int *list = new int[size];

If you go with the latter, you need to free it later on:

delete[] list;

arrays are faster, so I wanted to use arrays

This is not true. Where did you hear this from?
