Question

In a pretest loop, the control expression is evaluated before each iteration, including the first iteration.

a) True
b) False

Answer 1

A pretest loop evaluates the control expression before each iteration, including the first one, making option a) True the correct answer. While loops in programming languages like Java and Python are typical examples of pretest loops.

Step-by-step explanation:

In a pretest loop, the control expression is indeed evaluated before each iteration, which includes the first iteration. The correct answer to the question is option a) True. For example, in programming languages such as Java, C++, or Python, the most common pretest loops are while loops. Before any code within the loop is run, the condition at the top of the loop is checked. If the condition is true, the loop body executes. This process repeats itself until the control expression evaluates to false, at which point the loop terminates.
