以人类Person为基类公有派生学生类Student和教师类Teacher，main(void)函数完成对其的测试。

Person类结构说明：

Person类的数据成员包括：
①私有数据成员：身份证号no(char [20]型)，姓名name(char [20]型)。
Person类成员函数包括：
①有参构造函数Person(char *, char *)和拷贝构造函数Person(const  Person  &)，其中有参构造函数参数默认值为空串或0(当参数为NULL时视为空串处理)，输出信息“Person Constructor run”，拷贝构造函数输出信息“Person CopyConstructor run”
②析构函数，析构函数输出信息“Person Destructor run”
③公有函数成员：void  setNo(char *)和char * getNo()分别返回和设置身份证号no(当参数为NULL时视为空串处理)
④公有函数成员：void  setName(char *)和char*  getName()分别返回和设置姓名name(当参数为NULL时视为空串处理)
⑤公有成员函数void show() const用于显示人的基本信息，显示格式为：
No=身份证号,Name=姓名
