The program in this chapter isn’t really a game, but it is fun nevertheless. The program will convert normal English into a secret code. It can also convert secret codes back into regular English. Only someone who knows the key to the secret codes will be able to understand the messages.

Because this program manipulates text to convert it into secret messages, you’ll learn several new functions and methods for manipulating strings. You’ll also learn how programs can do math with text strings just as they can with numbers.
