Exercise 5 - due at 11:59:00 PM EDT on 09/14/2021

All 3 problems can be solved in the same program

1. Write a C++ program that displays a menu to the user, and reads in a character as a choice. If the choice were 'a', read in 2 integers. If both numbers are greater than 100, add them. Otherwise, multiply them. If the choice were 'b', read in 3 doubles. If any of them is 0, print their sum. Otherwise, print their product. 

2. The in-class example for the pass/fail if...else statement chooses to equally weight the midterms and the final. Modify the code snippet to change that by
a. Reading in 3 values for exams instead of 1: mid1, mid2, and fin
b. Calculae the total by just adding these 3 variables to "total" instead of "exam"
c. Calculate the mileAvg as ((mid1/12 + mid2/12 + fin/15)/3)*100

3. 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".


Sample Output:
Here, each part was run separately, multiple times. This is just to help with testing. Your program should only produce 1 output per run of the problem.
