WARNING: This program has a logic error. It doesn't cause an error message, but something isn't quite right.
modulo% calculates the remainder of division! This program splits up candy among a group of friends and calculates how much candy is leftover.
Click Run and enter a number between 1 and 10. Look at the stage. What's wrong with the output?
Fix the program by replacing the division operator / with the modulo operator %.
