In this problem, you will also define a GradeType enumeration which will include a predefine set of categories, e.g. Final, Midterm, Quiz, Project, and Homework.
Users will select from the following options: I, D, P, or Q, which correspond to insert, delete, print, or quit respectively. (Hitting Q will exit the application.) [5]
Use the following formula as a guide:
Final Grade = 0.22 * (Final Exam PE / Final Exam PP) + 0.18 * (Midterm PE / Midterm PP) + 0.10 * (Quizzes PE / Quizzes PP) + 0.20 * (Project PE / Project PP) + 0.30 * (Homework PE / Homework PP);
