This article mainly introduces how to use C++ code to achieve the relevant knowledge of the school personnel management system, the content is detailed and easy to understand, the operation is simple and fast, and has a certain reference value. I believe that you will gain something after reading this article on how to use C++ code to achieve the school personnel management system. Let's take a look.

Topic requirement

School personnel management system

1. Establish a school class, which defines the increase function of adding personnel according to their names, the deletion function of personnel and the query function (subject to the name).

2. Establish a personnel base class with name and gender attributes and an output function (which can be defined as a virtual function).

3. Establish an employee class and a student class, both of which are inherited from the personnel class. Requirements: you can output the attributes of the employee class (student class) object (such as name, gender and work permit number or student number), and write the specific implementation of their output function respectively.

4. Overload "> >" and use cin to assign values to employee class, student class and on-the-job student class. (choose to do)

5. Write the main () main function, test the above functions, and add, delete and query all kinds of people in the way of menu (with the name as the clue).

6. The program should adopt multi-file structure.

7. Vs2019 compilation
