Assignment Description:
Write a program for keeping a course list for each student in a college. Information about each student should be kept in an object that contains the student id (four digit integer), name (string), and a list of courses completed by the student.
· The course taken by a student are stored as a linked list in which each node contain course name (string such as CS41, MATH10), course unit (1 to 4) and the course grade (A,B,C,D,F).
· The program provides a menu with choices that include adding a student record, deleting a student record, adding a single course record to a student’s record, deleting a single course record from a student’s record, and print a student’s record to a screen.
· A student record should include a GPA (Grade Point Average) when display on the screen. The GPA is calculated by following formula:
· When the user is through with the program, the program should store the records in a file. The next time the program is run, the records should be read back out of the file and the list should be reconstructed
· You will need to implement a List container to hold a list of student records, each of which has a List container as its member. Note that no duplicate items should be permitted in either (student and course) List container.
· Develop a test driver program that allow options to add, remove, and display student records and the course list of each student.
· You may use class template technique (in C++) or generic programming (in Java) to implement a List ADT that could be used for both student list and the course list..
· To calculate G.P.A. for one term:
1. Multiply the point value of the letter grade (A=4, B=3, C=2, D=1, F=0) by the number of credit hours. The result is the grade points (quality points) earned.
2. Total the credit hours for the student; total the quality points for the student.
3. Divide the total quality points by the total credit hours.
