/*
Using the program you developed for Homework 1, define a structure which supports the following types of information:
- student name
- student ID number
- current exam grade
- prior exam grade
- overall GPA
The user will once again identify the number of students being represented and will then provide the 5 pieces of information for each student.
The user can sort based on any one of the 5 criteria, by specifying a value of 1-5.
After sorting, print the result.
