Question
Program 24 "Sorting Students" Write a C++ program that will open a file named stDATA.txt. This file contains an unknown number of student records, one per line. The total number of records will be less than or equal to 100. Your program should print a list of students sorted by GPA. If two students have the same GPA they should be sub-sorted by classification (SR, JR, SO, FR). If two students have the same GPA and the same classification, they should be sub-sorted by last name. If two students have the same GPA, classification, and last name they should be sub-sorted by first name. If two students have the same GPA, classification, last name and first name, the second student's record should not be printed; instead the message: "I THINK THIS IS A DUPLICATE RECORD" should be printed.
