Newline

Notice the difference between prog1 and prog2 (example 2). Prog2 in the last output statement has the following:

cout << "Liters =" << liters << "$\backslash$ n";

where << "$\backslash$ n" is used to generate new line. To put a newline character into a string, use "$\backslash$ n". In addition to using the newline character to advance the cursor, you can use the

symbol in the identical way.
