I am trying to edit my current homework assignment to include a loop that lets the user repeat the computation for new values until the user says they want to end the program. I was given a hint to use integer division and the % operator to implement this function. I have created the program from scratch and researched my book for the last 3 hours (plus online), but cannot figure out how to use integer division and modulus as a loop control. Can someone help explain it to me? Below is the code I have written (it compiles and runs with no errors), and it exits properly if the integer entered is more than 100 or less than zero. Any guidance would be a great help, or a link to C++ documentation describing how to use int division and modulus as a loop control.

Thank you,
