These are dynamic arrays in C++
Usage
#include <vector>
vector<string> cars;
vector<string> cars2 = {"Volve", "BMW", "Ford"};
for (string car : cars2){
cout << car << "\n";
}
cout << cars2[0]; // returns 1st element
cout << cars2[1]; // returns 2st element
cout << cars2.at(0); // returns 1st element and handles errors
cout << cars2.at(9); // returns 9th element and handles errors
cout << cars2.front(); // first element
cout << cars2.back(); // last element
cars2.push_back("Mazda"); // add a element to the back
cars2.pop_back(); // remove an element to the back
cars2.size() // returns the length of the vector
