Exercise 6 - 01/30/2017

Write a C++ program to print grade ranges for a particular letter grade in the class. Use the class syllabus for the grade ranges. You only need to consider the "letter". You can ignore the "+" and "-". For example, C+, C and C- would be considered the same grade. If the letter grade is not valid, print an error message.

Enter the letter grade : B

The grade was between 80 and 89.99

2.

Enter the letter grade: K

Invalid letter grade.

3. 

Enter the letter grade: A

The grade was over 90
