项目一

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;  }

运行结果

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;    }
