Answer 3

I would just use push_back() for each item for now.

Vectors resize dynamically when ever new data is added.

You can use reserve [vector.reserve(size_t)] to make the vector array a certain size to increase the speed of adding items, but generally the speed gained is negligible.

Answer 4

also try out <string> instead of char arrays. :)

Answer 5

They are super easy. Think dynamically sized arrays.
