2.1 Introduction
As indicated in Chapter 1, writing a computer program involves two basic activities: (1) figuring out what you want to do and (2) writing code to do it. You might be tempted to skip the first step and jump imme- diately to the second step—writing code. Try to resist that urge. Jumping immediately into the code often
