Loops

Abstract

In this chapter, you’ll learn how you can repeat a block of statements until some condition is met. The programming mechanism for this is called a loop. The number of times that a loop is repeated can be controlled simply by a count—repeating the statement block a given number of times—or it can be more complex—repeating a block until some condition is met, such as the user entering “quit”, for instance. The latter would enable you to program the calculator example in the previous chapter to repeat as many times as required without having to use a goto statement.
