Chapter 5: Problem 3

Why are the statements in the body of a loop called conditionally executed statements?

Short Answer

Expert verified

#Short Answer# The term "conditionally executed statements" refers to the statements within a loop that are executed only when the loop's condition is true. Each time a loop iterates, it checks if the condition is true, and if it is, the statements inside the loop's body are executed again. These statements will not be executed once the condition becomes false, thus making the execution of these statements conditional upon the loop's specified condition.

Step by step solution

Introduction to Loops

Loops are programming constructs that repeatedly execute a block of code as long as a specific condition is true. The blocks of code executed within the loop are known as the body of the loop, and the statements inside the loop are called loop statements.

Conditional Execution

Conditional execution refers to running particular code statements or blocks based on whether a specific condition or set of conditions are met. In other words, the code will execute only when certain criteria are fulfilled.

Components of a Loop

In a loop, there are typically three main components: 1. Initialization: This is where variables are initialized and set to their starting values. This step happens before the loop begins. 2. Condition: This is a criteria that must be met for the loop to continue executing. As long as this condition is true, the loop will keep running. 3. Iteration: This typically includes updating the variable values at the end of each loop iteration, eventually leading to the condition becoming false and the loop being terminated.

Conditionally Executed Statements in a Loop

The statements in the body of a loop are referred to as conditionally executed statements because they will only be executed if the loop's condition is true. Each time the loop iterates, it checks if the condition is still true, and if so, the statements in the body will be executed again. If the condition becomes false, the loop terminates, and the statements within the loop body are no longer executed. So, the term "conditionally executed statements" emphasizes that whether or not these statements are executed depends on the loop's condition being true.
