(2)从People(人员)类派生出student(学生）类，添加属性：班号char chassNO［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（为（教师类内嵌子对象）；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． （３）对People类重载＂＝＝＂运算符和＂＝＂运算符，＂＝＝＂运算符判断两个People类对象的id属性是否相等；＂＝＂运算符实现People类对象的赋值操作． （４）定义一个对People类对象数组按编号排序的函数，一个按编号查找people对象的函数． （５）设计主控模块程序． （６）对给出的程序源代码要给出各部分的详细注释． 相关程序代码为：这是我的课程设计，大家可以参考一下哦！不足之处还请大家多多指点哦！！！ #include<iostream> #include <string.h> using namespace std;
