Add a number in a Vector

// CPP program to illustrate

// push_back() function

#include <iostream>

#include <vector>

using namespace std;

int main()

{

vector<int> myvector{ 1, 2, 3, 4, 5 };

myvector.push_back(6);

// Vector becomes 1, 2, 3, 4, 5, 6

for (auto it = myvector.begin(); it != myvector.end(); ++it)

cout << ' ' << *it;

}
