Undergraduate Students $-$ Undergraduate students have the following properties:

Name, StudentNumber, Major, and Level $($Freshman$,$ Sophomore, Junior, Senior$)$

Graduate Students $-$ Graduate students have the following properties:

Name, StudentNumber, Major, and Degree $($Master$,$ Doctoral$)$

Instructors $-$ Instructors have the following properties:

Name, ID$,$ Salary. However, the salary is a property in the job class. See Slide $27$ from Introduction to Class InheritanceOpen this document with ReadSpeaker docReader PowerPoint Presentation.
