• Switch statement

• While loop

• For loop

• If statement

What is the main component of while loops that determines if the loop will run or not?

• Integer value

• String expression

• Boolean expression

• Character variable

Where should the loop control variable be declared and initialized in a while loop?

• At the end of the program

• Before the while loop

• Inside the loop body

What happens if the Boolean expression in a while loop always evaluates to true?

• The loop becomes an infinite loop

• The loop never executes

• The loop body is not executed at all

• The program crashes

When should a for loop be used instead of a while loop?

• When the loop body is complex

What is the purpose of a while loop?
