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 10 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:
setLab : 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.
setPassFailExam : 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.
setEssay : 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.
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 should refer-
ence this object.
print : This function should display the numeric scores and grades for
each element in the grades array.
Demonstrate the class in a program.
