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

• To execute a block of code based on user input

• To execute a block of code only once

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

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

Which of the following best describes the condition in a 'while' loop?

• It is not necessary for a 'while' loop

• It is checked after the loop executes

• It is checked before each iteration of the loop

• It is checked only once at the start

What happens if the condition in a 'while' loop is always true?

• The loop will execute a fixed number of times

• The loop will never execute

• The loop will execute only once

• The loop will execute indefinitely

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

• When you know the exact number of iterations needed

• When you want to execute code without any condition

• When the number of iterations depends on a condition

• When you need to iterate over a collection

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

• When you need to iterate a known number of times

• When you need to process user input until they quit

• When you need to repeat a task until a condition changes

• When you need to perform a task while a condition is true
