loops

Question 1

The while loop

Answer 1

The while loop is a pretest loop. It is ideal in situations where you do
not want the loop to iterate if the condition is false from the beginning. It is also ideal
if you want to use a sentinel value to terminate the loop.

Question 2

The do-while loop

Answer 2

The do-while loop is a posttest loop. It is ideal in situations where
you always want the loop to iterate at least once.

Question 3

The for loop

Answer 3

The for loop is a pretest loop that has built-in expressions for initializing, testing, and updating. These expressions make it very convenient to use a loop
control variable as a counter. The for loop is ideal in situations where the exact number of iterations is known.
