Help with my Grade Project - Fixed

Code:

// Name: grade.cpp
// Author: Joel Zimmerman

// Description: Output's a letter grade based on the input of a percentage

// Thanks to Rob for the idea

// Note: the Case 10, Case 9 with the Break, took FOREVER to figure out.

It doesn't seem to work as it should.
