第十一周项目2-职员有薪水了

标签：

（1）定义一个名为CPerson的类，有以下私有成员:姓名、身份证号、性别和年龄，成员函数：构造函数、析构函数、输出信息的函数。并在此基础上派生出CEmployee类，派生类CEmployee增加了两个新的数据成员，分别用于表示部门和薪水。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。

（2）字符串除了用C++扩充的string类型外，按C语言的传统，还可以用char *表示。请将类声明中的string全部改为char *后，重新写一遍程序（此时的区别是，类中有指针成员，构造和析构函数需要考虑深复制的问题了。）
