Question

Answer each of the following questions about loops in C++. In each question, LABEL the three parts of the loop.

a.) Write a while statement that will ask the user for integers until the user enters the sentinel value of -1. Declare all needed variables.

b.) Write a for statement that will print out all the multiples of 3 between 1 and 200. Declare any needed variables.

c.) Write a do while loop that will ask the user for characters and end when the character is equal to 'e'. Declare any needed variables.
