Exercise 7 - Due at 11:59:00 PM on 09/14/2021

Both problems can be solved in the same program. 

1. Write a C++ program to read in a time (only the hour, in millitary time). If the time is before noon, print "Good Morning". If it is between noon and 6 PM, print "Good Afternoon". Otherwise, print "Good Evening".

2. 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.
