Write a class named CourseGrades. The class should have a member named grades that is an array of GradedActivity pointers. The grades array should have four ele- ments, one for each of the assignments previously described. The class should have the following member functions: This function should accept the address of a GradedActivity object as its argument. This object should already hold the stu- dent's score for the lab activity. Element 0 of the grades array should reference this object. setLab: This function should accept the address of a PassFailExam object as its argument. This object should already hold the stu- dent's score for the pass/fail exam. Element 1 of the grades array should reference this object. setPassFailExam: This function should accept the address of an Essay object as its argument. (See Programming Challenge 6 for the Essay class. If you have not completed Programming Challenge 6, use a GradedActivity object instead.) This object should already hold the student's score for the essay. Element 2 of the grades array should reference this object. setEssay: setPassFailExam: This function should accept the address of a FinalExam object as its argument. This object should already hold the student's score for the final exam. Element 3 of the grades array shoulc reference this object. This function should display the numeric scores and grades fo each element in the grades array. print: Demonstrate the class in a program.

Object Oriented Programming System (OOPs) is a programming model built on the perception of “objects” that contains data and methods. The major purpose of Object Oriented Programming is to increase the maintainability and flexibility of programs. Object Oriented Programming gets together data and its behavior (methods) in a single location (object) which makes it easier to understand.
