It serves to send usually text-based information on the monitor (in currently running application, window), for instance:

...

int myVariable;

cout >> "Please enter a number: ";

cin >> myVarible;

//You entered number 5

cout << "You entered the number: " << myVariable;

...

In the application window you will see:

Please enter a number:

5

You entered the number: 5
