虚基类——(1)定义人员类Person: 公有成员:姓名(Name); 保护成员:性别(Gender),年龄(Age); 构造函数和析构函数...

题目描述:

(1)定义人员类Person:
公有成员:姓名(Name);
保护成员:性别(Gender),年龄(Age); 

构造函数和析构函数 

(2) 从人员类Person派生学生记录类StudentRecord:
添加公有成员:学号(Number),班级(ClassName),
添加静态公有成员:学生总人数(TotalCount);
添加保护成员:平均成绩(Score);
实现构造函数和析构函数。
(3) 从人员类Person派生教师记录类TeacherRecord:
添加公有成员:学院(CollegeName),系(DepartmentName);
添加保护成员:教龄(Year);
实现构造函数和析构函数。 

(4)从学生记录类StudentRecord和教师记录类TeacherRecord派生学生助教类TeachingAssistant:
添加公有成员:辅导课程(LectureName);
实现公有函数:显示人员信息(Show),屏幕打印 姓名,性别,年龄,学号,班级,学生总人数,平均成绩,学院,系,教龄,辅导课程。
实现构造函数和析构函数。为检验类间结构设计是否正确,设计函数void SetName(String name)实现更改一名助教的姓名的功能。

创建一个助教类的对象

助教
姓名 性别 年龄 学号 班级 平均成绩 学院 系 教龄 辅导课程
郑七 男 22 2010123 软20101 89         信息 软件    1 数据结构
显示其信息。

调用更改姓名的函数,更改其姓名为“郑八”,并再次显示其信息。

输入

输出

显示构造的信息和更改前和更改后的助教信息

样例输入

 

样例输出

Person郑七constructed
Student郑七constructed
teacher郑七constructed
teachingassistant郑七constructed
Name:郑七 Gender:男 Age:22 Number:2010123 ClassName:软20101 TotalCount:1 Score:8
9 CollegeName:信息 DepartmentName:软件 Year:1 LectureName:数据结构
Name:郑八 Gender:男 Age:22 Number:2010123 ClassName:软20101 TotalCount:1 Score:8
9 CollegeName:信息 DepartmentName:软件 Year:1 LectureName:数据结构
teachingassistant郑八destructed
teacher郑八destructed
Student郑八destructed
Person郑八destructed

提示

各类的构造函数和析构函数都有输出。

调用公有函数Show,以分别显示各个记录的人员信息。

在派生助教类时,使用虚基类。
