Answer 1

I don't get the question much but I'll assume the following would answer your question.

That's quite simple, just include the container you want to use. For example:

#include <array>
#include <vector>
// And so on based on what containers you would need.

And as a sample of using them hmm... Assume you have a C-styled array

int a[3] = {1, 2, 3};

If you're gonna make it in the C++ Array container it would be something like:

array a<int, 3> = {1, 2, 3};

Take note it would make more sense to you if you know the Templates which is at the last part of the C++ Tutorial in SoloLearn.
