请在下面程序的横线处填上适当内容,以使程序完整,并使程序的输出为:
Name: 龙三

Grade: 19

#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;  
}

项目三

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);    
    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<<" ";  
    cout<<m_szId<<" ";  
    cout<<m_nSex<<" ";  
    cout<<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;    
}
