CHAPTER 43 — More Ways to Make Decisions

Chapter Topics:

Nested if and else statements can be used to choose between any number of options. But, using nested statements is sometimes awkward. This chapter discusses two other statements that choose between several options.

Neither of these two statements does anything that can't be done with ifs and elses. But they are sometimes useful, and you will need to know them to understand programs written by other programmers.

Some programmers avoid using these statements. Neither statement is used in the AP Computer Science test. This entire chapter may be skipped. These statements are not used in the chapters that follow.
