Vector

Example 1:
Create a vector that holds string values. Print the size and first, second, third and last elements. Finally using a for each loop print all the elements to the console screen.

#include <iostream>

#include <vector>

#include <string>

using namespace std;

int main()

{

       vector<string> strVector = { "john", "Paul", "Jesse", "Patty" };

       cout << "Size of the Vector is " << strVector.size() << endl;

       cout << "The first item in the vector is " << strVector.front() << endl;

       cout << "The second item in the vector is " << strVector[1] << endl; //using substring

       cout << "The second item in the vector is " << strVector.at(2) << endl; //using at()

       cout << "The last item in the vector is " << strVector.back() << endl;

       for (auto&& s : strVector)

       {

              cout << s <<endl;

       }

       system("pause");

       return 0;
