CHAPTER 20 — Example Program

This chapter steps you through the creation of a small program that mimics the operation of a combination lock. The goals are for you to gain additional experience in programming, and to review several topics.

The chapter reviews:

• How to get an integer from the user.
• The if statement.
• The boolean data type.
• The while statement.

There are no new topics in this chapter, so you can skip it if you feel that you need no further practice.
