Rework your project to include a class. As explained in class, your project should have its functionalities moved to a class, and then create each course as an object to a class that inherits all the different functionalities of the class.
You createclass function should be used as a constructor that takes in the name of the file containing the student list.
(This way different objects are created with different class list files.)
Test out your program on at least 3 courses, each with a different file containing the class list.
