What is the primary purpose of a 'while' loop in programming?

• To execute a block of code a specific number of times

• To execute a block of code as long as a condition is true

• To execute a block of code only once

• To execute a block of code based on user input

Which of the following best describes how a 'while' loop operates?

• It executes a block of code only if a condition is false

• It checks a condition after executing the loop body

• It runs indefinitely without any condition

• It checks a condition before executing the loop body

What happens if the condition in a 'while' loop never becomes false?

• The loop will execute a fixed number of times

• The loop will execute indefinitely

• The loop will not execute at all

• The loop executes once and stops

Which scenario is best suited for using a 'while' loop?

• When you need to iterate over a collection

• When you need to execute code based on a switch statement

• When you need to execute code until a condition changes

• When you know the exact number of iterations needed

In which situation would a 'while' loop be inappropriate?

• When the loop should execute based on a condition

• When the number of iterations is known beforehand

• When the loop needs to run until a condition is met

• When the loop should run indefinitely
