Question

(C++ Language, Class files) Write a program for keeping a course list for each student in a college. The information about each student should be kept in an object that contains the student's name and a list of courses completed by the student. The courses taken by a student are stored as a linked list in which each node contains the name of a course, the number of units for the course, and the course grade. The program gives a menu with choices that include adding a student's record, deleting a student's record, adding a single course record to a student's record, deleting a single course record from the student's record, and printing a student's record to the screen. The program input should accept the student's name in any combination of upper and lowercase letters. A student's record should include the student's GPA when displayed on the screen. When the user is through with the program, the program should store the records in a file. The next time out of the file and the list should be reconstructed.
