第11周项目-2.2
//私有成员:全名、身份证号、性别和年龄
//会员功能:构造函数、析构函数、功能输出信息。
//在此基础上,来自CEmployee分类。派生类CEmployee我们增加了两个新的数据成员,它们被用来代表部门和薪水。
//要求派生类CEmployee的构造函数显示调用基类CPerson的构造函数,并为派生类CEmployee定义析构函数,定义输出信息的函数。
//字符串除了用C++扩充的string类型外。按C语言的传统,还能够用char *表示。
//请将类声明中的string所有改为char *后,又一次写一遍程序(此时的差别是,类中有指针成员,构造和析构函数须要考虑深复制的问题了。)
