Grades processing program:

140 students
15-20 hw grades per student
15-20 max grades for each hw part
midterm grades per student
final exam grades per student


Approach #1: Imperative Solution
- #students (140)
- #hw parts (20)
- 2D array of 140 students (rows) x 20 hw parts
- max scores:
   - put max scores in 0 row of hw grades table or
   - create another array of 20 hw max grades
- 2D array of 140 students (rows) x 2 exam grades

Approach #2: Object-Oriented Solution
Define Student
	- array of 20 hw parts
	- midterm
	- final exam
	- hw avg
	- course grade
	- letter grade
Define Course
	- array of 20 max hw grades
	- array of 140 Students
