Question

The instructor want us to write a program that can re displays the menu only when the user wants to restart a selection and add an option to continue with another selection.

The problem I have is when the user select a number from 1 to 4 and complete the selection, the program will ask the user if the user want to continue with another selection and when the user says no, the program still ask to select a number without ending program.

This what of I want on my program: The user select a number from 1 to 5. When the user select that number, the user will be asked " Do you want to continue another selection? (Y/N)" If the user says Yes, then the program will ask to select a number from 1 to 5. However, if the user says No, then the program will exit. But I having trouble on making program to do that.

So far I have this old code: http://www.mediafire.com/view/cozrcxi7xi58df1/lab8.txt

I try many things to figure out but cant get NO part to exit the program

Explanation / Answer

please rate - thanks
