The system is able to find grade for each course based on final marks, calculate GPA, Calculate CGPA.
Methods (menu);
i. Input matric_number, name, coursecode, credithours, semester, final marks for each subject. You may use text file ii. Calculate GPA and CGPA for each student. iii. Search a student record iv. Print Report for all students order by CGPA ascending
Any way to implement linked list?
