Problem description and functional requirements

1. Problem description

There are four types of staff in a university: teachers, experimenters, administrators, teachers and administrators; the common information includes: number, name, gender, age and so on.

Code implementation with comments

Don't talk nonsense, direct code, welcome to correct.
