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 exaam that has 10
questions. The minimum passing score is 70. • An essay that is
assigned a numeric score. • A finalexam 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.
