Textbook Question
Chapter 7, Problem 4SA
In this chapter you saw how a posttest loop can be used in input validation, as an alternative to the priming read followed by a pretest loop. Why is it typically not best to use a posttest loop approach?

Is it feasible to modularize input validation using Boolean methods? Why is this happening, or why is it not happening?
Two kinds of loops occur frequently in programming: counter-controlled loops and
sentinel-controlled loops.
Explain each kind of loop in terms of its implementation with your own examples.

We simply check either break or continue flags to see if either is set We simply check break variable to see if used. we check the for flag to see if loop terminated correctly Since there is no way for a loop in Java to tell you if it completed without breaks or continues, you'd need to set a boolean flag to indicate that and check it after the loop was completed.arrow_forwardWhy and how does debugging even help?
