CHAPTER 18 — Sentinel Controlled Loops

Chapter Topics:

Sentinel-controlled loops
Example programs:
- Adding up a list of integers
- evaluating polynomials
Using an if-else statement inside the loop body
Matching up if's with else's
Using a String value as a sentinel

The previous chapters have discussed loops in general, and counting loops in particular. The same statements that are used to build counting loops are used to build other kinds of loops. This chapter looks at a kind of loop called a sentinel controlled loop.

QUESTION 1:

Say that you want a program that adds up any number of integers entered from the keyboard. Will a loop be used in this program?
