#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)参考教材P169加底纹部分{public:    Student(string s, int g):Person(s) // (2)    {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;}
【项目3 - 职员薪水】
   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、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定义输出信息的函数。


#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):m_szName(name),m_szId(id),m_nSex(sex),m_nAge(age){}    void Show1(){string sex=(m_nSex)?"男":"女";cout<<m_szName<<"   "<<m_szId<<"      "<<sex<<"      "<<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):CPerson(name,id,sex,age){m_szDepartment=department;m_Salary=salary;}    void Show2(){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;cout<<"姓名    ID    性别    年龄    部门    薪水"<<endl;    CEmployee employee1(name,id,sex,age,department,salary);    employee1.Show2();    return 0;}
