Course Grades In a course, a teacher gives the following tests and assignments: • A lab activity that is observed by the teacher and assigned a numeric score. • A pass/fail exam that has ten questions. The minimum passing score is 70. • An essay that is assigned a numeric score. • A final exam that has 50 questions.
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: setPassFai1Exam: 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. 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: setPassFail Exam: 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 should reference this object. This function should display the numeric scores and grades for each element in the grades array. print: Demonstrate the class in a program.
