Question

The while loop requires the use of parentheses around the loop control expression.

a) True
b) False

Answer 1

The use of parentheses around the loop control expression in a while loop is true. While loops continue to execute as long as the condition within the parentheses is true.

Step-by-step explanation:

The statement that a while loop requires the use of parentheses around the loop control expression is true. In many programming languages, including widely-used ones such as C, C++, Java, and Python, the syntax for a while loop includes a condition within parentheses that determines whether the loop will continue to execute or terminate. Here is a basic example:

while (condition) {
// Code to execute while the condition is true
}

In this structure, the loop will repeatedly execute the block of code as long as the condition within the parentheses evaluates to true. Once the condition evaluates to false, the while loop will stop executing. It is crucial to ensure that the condition can eventually become false, otherwise, the loop could become an infinite loop, causing the program to run indefinitely.
