Input

Now that we know how to give names to values, we can have the user of the program input values. This is demonstrated in line 6 below:

#include<iostream>
using namespace std;

int main () {
    int x ;
    cin >> x ;
    cout << x / 3 << ' ' << x * 2;

    return 0;
}

Just as cout << is the syntax for outputting values, cin >> (line 6) is the syntax for inputting values.
