C++作业4

问题及代码

（1）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( ) {
Person::display();   //  (3)
cout<<"Grade: "<<grade<<endl;
}
private:
int grade;
};
int main( )
{
Student s("龙三",19);
s.display1();//     (4)
return 0;
}

（2）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.h>
#include <iomanip>//setw:设置输出数据的宽度,使用时应#include <iomanip.h>
using namespace std;
class CPerson
{
protected:
string m_szName;
string m_szId;
int m_nSex;//0:women,1:man
int m_nAge;
public:
CPerson(string name,string id,int sex,int age);
void Show1();
~CPerson();
};

class CEmployee:public CPerson
{
private:
string m_szDepartment;
double m_Salary;
public:
CEmployee(string name,string id,int sex,int age,string department,float salary);
void Show2();
~CEmployee();
};

m_szId=new char[30];
for(int j=0;j<30;++j)

m_nAge=age;
}

CEmployee::CEmployee(char *name,char *id,int sex,int age,char *department,float salary):CPerson(name,id,sex,age)
{

m_szDepartment[i]=*(department+i);
m_Salary=salary;
}
void CPerson ::Show1()
{

}

void CEmployee::Show2()
{
cout<<setw(6)<<"name"<<setw(19)<<"id"<<setw(9)<<"sex"<<setw(7)<<"age"<<setw(12)<<"department"<<setw(8)<<"salary"<<endl;
Show1();
cout<<setw(11)<<m_szDepartment<<setw(9)<<m_Salary<<endl;
}
