Conditional Structures and Loops

In this chapter, we start by describing how programmers can control the execution paths of programs using various branching conditionals and looping structures. These branching/looping statements act on blocks of instructions that are sequential sets of instructions. We first explain the single choice if else and multiple choice switch case branching statements, and then describe the structural syntaxes for repeating sequences of instructions using either the for, while or do while loop statements. We illustrate these key conceptual programming notions using numerous sample programs that emphasize the program workflow outcomes. Throughout this chapter, the leitmotiv is that the execution of a program yields a workflow of instructions.
