c++作业4

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;
}
