The vector is a simple data structure that allows you to store values with the same data type in one container.
Introduction
Without the use of a data structure, how would you store multiple variables? Let’s say we wanted to store 5 names into strings. How would this be done?
string name1,name2,name3,name4,name5;
cin >> name1 >> name2 >> name3 [...]
