Transcribed Image Text:11. 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.

Transcribed Image Text: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
