Bonus Marks Questions: Suppose you want to add these functionalities into your program: i) A teacher can now assign grades (numeric grade on a scale 4.0) to the courses he teaches. ii) The students can only see their grades when a teacher posts the grade iii) When the grades of all courses known to a student a cgpa is calculated for the courses he has taken so far. Hints for Bonus Marks Questions: 1. You can create a class Grade which will hold a particular student and his grade (numeric grade) in a particular course, modify the class Course and add the fields that you think will be necessary to implement the system for a faculty to assign grades to the courses he teaches. Also, modify Student Class so he can see the grades of the courses he has taken. 2. You can use a flag. Implement a method which will check whether the grades for a specific course is posted or not for a specific student, and implement the logic. 3. You can use the flags for different courses a student has taken. The cgpa is calculated with previous cgpa and the current semester's gpa.
