Question

This is a C++ Program, I need the program broken up into Student.h, Student.cpp, GradeBook.h, GradeBook.cpp, and Main.cpp

1. The system must be able to manage multiple students (max of 5) and their grades for assignments from three different assignment groups: homework (total of 5), quizzes (total (total of 2) of 4), and exams 2. For each student record, the user should be able to change the grade for any assignment These grades should be accessible to the gradebook for calculations, but not visible or directly mutable outside ofthe student record 3. The gradebook should know the name of the course. It should also know the weights of each assignment group and be able to print a report to the screen. This report should contain the course name and a well-formatted table containing columns for the student names, and for each assignment group. The group weights should be displayed (as a percentage) to the name of each assignment group in the table's header. It should be possible to add and remove students from the gradebook. Removals from the gradebook should shift each successive student "up" gradebook, the remaining students starting with student 4 should be moved up a slot (1e next in the list. For example, if student 3 is removed from the student 4 to student 3's old slot, student 5 to studet 4's old slot, etc.) 4. A user interface should be created with a menu system used to navigate the functionality necessary to complete the stated requirements. It is recommended to use a numbering scheme when prompting the user for their desired action. See the end of this project sheet for a reference you may use for the menus 5. All names (student names, gradebook name) should be set to "" prior to being by the user. This could also be used in logic to determine whether or not a student entry in the gradebook is "valid". Empty student slots should not be displayed in require the user to identify a student record to modify 6. The gradebook should be able to calculate class averages from the student records. The averages are the sum of the valid grades divided by the total number of valid grades for that group (ie. ungraded assignments Since each student record could contain a different number of grades for each category, the class average should be computed assignment group as homework grade (note, not a zero), then their homework average should be comprised of 4 grades instead of 5. When computing the class average homework grade student's average homework grade for the running total, then use that total to compute the average. When computing the average final grade, don't forget 7. See the grading breakdown for additional requirements simple set menus that are not part of the total number of valid grades) as the average of each student's average for each well as their final grade. For example, ifone student if missing a single each use to use the group weights Sample UI MAIN MENU |=- 1. Add a student 2. Remove a student 3. change a student's grade 4. change group weights 5.
