Design and code a program that asks the user how many numbers from which to determine an average. Then prompt the user for the integer values and sum them to a total. Display the sum of the numbers and the calculated average with appropriate accompanying text. The average should be shown with 1 decimal place. Repeat the process until the user enters zero (0) as the number of values to be averaged. You may use either a "while" loop or a "do…while" loop for the main program loop.
