问题描述:

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。

代码:

#include <iostream>
#include <cstring>
#include <iomanip>
using namespace std;

class CPerson
{
protected:
    string m_szName;
    string m_szId;
    int m_nSex;//0:women,1:man
    int m_nAge;
public:
    CPerson(string name,string id,int sex,int age);
    void Show1();
    ~CPerson(){};
};
CPerson::CPerson(string name,string id,int sex,int age):m_szName(name),m_szId(id),m_nSex(sex),m_nAge(age){}
void CPerson::Show1()
{
    cout<<setw(5)<<m_szName<<setw(20)<<m_szId;
    if(m_nSex==0)
    {
        cout<<setw(7)<<"women";
    }
    else cout<<setw(7)<<"men";
    cout<<setw(5)<<m_nAge;
}


class CEmployee:public CPerson
{
private:
    string m_szDepartment;
    double m_Salary;
public:
    CEmployee(string name,string id,int sex,int age,string department,double salary);
    void Show2();
    ~CEmployee(){};
};
CEmployee::CEmployee(string name,string id,int sex,int age,string department,double salary):CPerson(name,id,sex,age),m_szDepartment(department),m_Salary(salary){}
void CEmployee::Show2()
{
    cout<<setiosflags(ios::left)<<setw(5)<<"name"<<setw(20)<<"id"<<setw(7)<<"sex"<<setw(5)<<"age"<<setw(12)<<"department"<<setw(8)<<"salary"<<endl;
    Show1();
    cout<<setw(12)<<m_szDepartment<<setw(8)<<m_Salary<<endl;
}

int main()
{
    string name,id,department;
    int sex,age;
    double salary;
    cout<<"input employee's name,id,sex(0:women,1:man),age,department,salary:\n";
    cin>>name>>id>>sex>>age>>department>>salary;
    CEmployee employee1(name,id,sex,age,department,salary);
    employee1.Show2();
    return 0;
}

 

运行结果:

第10周项目2-职员有薪水了(1)_派生类
