(DEBUGGING PROGRAM)

Write a program to read from a file called courses.dat and store the information into a singly linked list.

The courses.dat file contains the following information Course number, year, semester, grades and credits.

The program must be interactive (menu-driven) and provide the following functionality:

1: Print Transcipt (All course information, total credits, total quality points, gpa)

2: Add a course

3: Delete a course

4: Print the transcript for specified semester
