In this project, you will write a software for the Registrar's office of a university called YouOIT to maintain information about students and courses at the university.

The registrar office maintains a master text file, called classes.txt. This file contains the names of all classes taught at the university. For each class, the registrar office keeps a file with ID numbers of the students who took that class and their final numerical grade in the class. The registrar office also keeps another master file, called students.txt, with the ID numbers and names of all the students registered at the university. The following figure shows an example of how the files look like:
