(1) Define the personnel class Person:
Public member: Name;
Protected members: Gender, Age;  

Constructors and destructors

(2) Derive student record class StudentRecord from Person class:
Add public members: student Number, class name,
Add static public members: total number of students (TotalCount);
Add protected members: average Score;
Implement constructors and destructors.
(3) Deriving teacher record class TeacherRecord from Person class:
Add public members: College name, department name;
Add protected members: Year;
Implement constructors and destructors.

(4) Derive student teaching assistant from student record class StudentRecord and teacher record class TeacherRecord:
Add public member: LectureName;
Realize public functions: display personnel information (Show), print name, gender, age, student number, class, total number of students, average score, college, Department, teaching age and counseling course on the screen.
Implement constructors and destructors. To check whether the inter class structure design is correct, the function void SetName(String name) is designed to change the name of a teaching assistant.

Create an object of the TA class

assistant
Name, gender, age, student number, average grade of class, faculty, Department, teaching age, counseling course
Zheng Qi, male 22, 2010123, soft 20101 89, information software 1, data structure
Display its information.

Call the function to change the name, change its name to "Zheng Ba", and display its information again.

nothing

Displays the information of the construction and the teaching assistant information before and after the change

Person Zheng Qi constructed Student Zheng Qi constructed teacher Zheng Qi constructed Name: Zheng Qi Gender: male Age:22 Number:2010123 ClassName: soft 20101 TotalCount:1 Score:8 9 CollegeName: information DepartmentName: software year: 1 legurename: data structure name: Zheng Ba Gender: male Age:22 Number:2010123 ClassName: soft 20101 totalcount: 1 score: 1 score Re: 8 9 collegename: informationdepartmentname: software Year:1 LectureName: data structure teachingassistant Zheng Ba designed teacher Zheng Ba designed student Zheng Ba constructed person Zheng Ba constructed

All kinds of constructors and destructors have output.

 

Call the public function Show to display the personnel information of each record respectively.

 

Use the virtual base class when deriving the TA class.

The correct code can't pass OJ, so I have to use this method
