Chapter 15, Problem 11PC
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 elements, 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 GradedActi vity object as its argument. This object should already hold the student’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 student’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 |
| setPassFailExam: | This function should accept the address of a Final Exam 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. |
| print: | This function should display the numeric scores and grades for each element in the grades array. |
Demonstrate the class in a program.
