#include <iostream>  #include <string>  using namespace std;  class Person{  public:      Person(string s){          name=s;      }      void display( ){          cout<<"Name: "<<name<<endl;      }  private:      string name;  };  class Student:public Person//(1)  {  public:      Student(string s, int g):Person(s)// (2)参考教材P169加底纹部分      {grade=g;}      void display1( ){          display();   //  (3)          cout<<"Grade: "<<grade<<endl;      }  private:      int grade;  };  int main( )  {      Student s("龙三",19);      s.display1();       //  (4)      return 0;  }  

二、职员薪水

#include<iostream>#include<string>using namespace std;class CPerson{protected:    string m_szName;    string m_szId;    int m_nSex;//0:女,1:男    int m_nAge;public:    CPerson(string name,string id,int sex,int age);    void Show1();};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<<m_szName<<" "<<m_szId<<"  "<<(m_nSex?"男":"女")<<" "<<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(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<<"姓名"<<" "<<"ID"<<" "<<"性别"<<"  "<<"年龄"<<"  "<<"部门"<<"   "<<"薪水"<<endl;    Show1();    cout<<m_szDepartment<<"  "<<m_Salary<<endl;}int main(){    string name,id,department;    int sex,age;    double salary;    cout<<"请输入雇员的姓名,ID,性别(0:女,1:男),年龄,部门,薪水:\n";    cin>>name>>id>>sex>>age>>department>>salary;    CEmployee employee1(name,id,sex,age,department,salary);    employee1.Show2();    return 0;}
