第11周 【项目2 - 职员有薪水了】(1)

问题描述：

（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。

1. class CPerson
2. {
3. protected:
4. string m_szName;
5. string m_szId;
6. int m_nSex;//0:women,1:man
7. int m_nAge;
8. public:
9. CPerson(string name,string id,int sex,int age);
10. void Show1();
11. ~CPerson();
12. };
13. class CEmployee:public CPerson
14. {
15. private:
16. string m_szDepartment;
17. double m_Salary;
18. public:
19. CEmployee(string name,string id,int sex,int age,string department,double salary);
20. void Show2();
21. ~CEmployee();
22. };
23. int main()
24. {
25. string name,id,department;
26. int sex,age;
27. double salary;
28. cout<<"input employee‘s name,id,sex(0:women,1:man),age,department,salary:\n";
29. cin>>name>>id>>sex>>age>>department>>salary;
30. CEmployee employee1(name,id,sex,age,department,salary);
31. employee1.Show2();
32. return 0;
33. }

下面的运行结果供参考：
