C++作业4-1

一、问题及代码

【项目1 - 龙三】

#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;
}
