实验目的

学习声明和使用类的继承关系，声明派生类
熟悉不同继承方式下对基类成员的访问控制
学习利用虚基类解决二义性问题

实验任务

参考实验指导书第七章的实验任务4：

从实验 6 中的 people（人员）类派生出 student （学生）类，添加属性：班号 char classNO[7]；
从 people 类派生出teacher（教师）类，添加属性：职务 char principalship[11]、部门 char department[21]。
从 student 类中派生出 graduate（研究生）类，添加属性：专业 char subject[21]、导师 teacher adviser；
从 graduate 类和 teacher 类派生出 TA（助教生）类，注意虚基类的使用。重载相应的成员函数，测试这些类。

（类之间的关系如下图所示。）

实验步骤

创建一个教师实例，姓名为Zheng Li，编号为1001，性别为Female，1978年1月1日生，身份证号为1234567890，职务为professor，部门为CST。
创建一个助教实例，姓名为Li Chao，编号为011401，性别为Male，1988年6月1日生，身份证号为12345619880601，职务为TA，部门为CST，班号为cst61，专业为computer science，导师为Zheng Li。
依次输出该助教的姓名，编号，部门，班号，专业和导师。

编程要求

根据提示，在右侧编辑器补充代码，并输出正确的值。

测试说明

平台会对你编写的代码进行测试：
预期输出： TA name: Li Chao No.: 011401 Department: CST Class No.: cst61 Subject: computer science Advisor: Zheng Li

开始你的任务吧，祝你成功！
