Write a class Assignment that has private attributes for Name, Possible Points and Earned Points

Write a class Student that has private attributes for name and a vector of assignments. The constructor method should require a name. Add a method for get total score that returns the total number of points earned divided by the total number of possible points for their assignments.

Write a class Gradebook that has a vector of students and methods for print highest scoring student, that prints the student with the highest score, print lowest scoring student, print class average, add student ( accept a student reference to add ), score student ( that asks for a student name and prompts for scores for their assignments ), add assignment ( that adds an assignment with a 0 score for all students if there already isn\'t an assignment with that name ), print student list summary ( print the list of students and total score), print student detail ( print the list of students and every assignment score ).

Allow the user to Save ( write a file ) or Load ( read a file ) a gradebook.

Add a main method that has a looping menu allowing them to Add Students to the Gradebook, Add Assignments to the Gradebook, and all the other Gradebook functions.

This is what i have so far:
