Can someone give me an example of a situation when vectors are used?

Question

I remember reading that vectors are used when there is a lot of data that can't be stored inside an array. But in what situation will I need this.

When collecting server infomation or something else?

Also what's the limit in which an array can hold?

If anyone knows please explain.

Answer 1

EvilErrorPlayz Gaming vectors are used when you are not aware about size of array initially..

just push_back for each entry and you don't have to be sure about size of entries to be entered into vector from starting itself.
