As the regional manager of Wallly-Mart, you should like to create a report that tracks the sales of the 4 districts in the region you oversee. Each district is comprised of multiple stores. Write a program that prompts the user for a district number, 1 through 4 then allows the user to enter up to 6 of the store sale amounts. The program should continue allowing the entry of districts and store amounts until the user enters 0. After you have completed the sales entries, display the total for each district along with the projected sales if the total for each district should also be displayed.
