It’s all about building blocks. This chapter was about the basic building blocks that are used to construct computer programs. In addition to keywords, you use variables and operators to build statements. In turn, a computer program consists of a sequence of statements.
If you know how to build statements, then you know how to construct the basic building blocks of any computer program.
In Chapter 3, “ Using Conditional Statements,” you’ll start to look at statements that are a bit more complicated than those presented in this chapter because they involve conditional evaluation, or a choice, often depending on the user’s input.
