Chapter Summary 83 Note that you never absolutely need a break or continue statement. The programs in Displays and can be rewritten so that neither uses either a break or continue statement. The continue statement can be particularly tricky and can make your code hard to read. It may be best to avoid the continue statement completely or at least use it only on rare occasions. NESTED LOOPS It is perfectly legal to nest one loop statement inside another loop statement. When doing so remember that any break or continue statement applies to the innermost loop or switch statement containing the break or continue statement. It is best to
