4. Control Statements: Part 1

Objectives

In this chapter you'll learn:

  • To use the if and if...else selection statements to choose among alternative actions.

  • To use the while repetition statement to execute statements in a program repeatedly.

  • Counter-controlled repetition and sentinel-controlled repetition.

  • To use the increment, decrement and assignment operators.

Let's all move one place on.
