程序填空题：包含子对象的派生类构造函数
根据所定义的基类，定义派生类，请填空完成程序的功能
```c++
#include
#include
using namespace std;
class Student //声明基类
{public: //公用部分
Student(int n,string nam) //基类构造函数
{num=n;
name=nam;
}
void display() //输出基类数据成员
{cout<<"num:"< protected: //保护部分
int num;
string name;
};
class Student1: public Student //用public继承方式声明派生类student
{public:
@@[Student1(int n,string nam,int n1,string nam1,int a,string ad):Student(n,nam),monitor(n1,nam1) ](2) //派生类构造函数
{age=a; //在此处只对派生类新增的数据成员初始化
addr=ad;
}
void show( )
{cout<<"This student is:"< display(); //输出num和name
cout<<"age: "< cout<<"address: "< }
void show_monitor() //输出子对象的数据成员
{cout< monitor.display(); //调用基类成员函数
}
private: //派生类的私有数据
Student monitor; //定义子对象(班长)
int age;
string addr;
};
int main( )
{Student1 stud1(10010,"Wang-li",10001,"Li-sun",19,"115 Beijing Road,Shanghai");
stud1.show( ); //输出第一个学生的数据
stud1.show_monitor(); //输出子对象的数据
return 0;
}
```
###程序输出如下
```
This student is:
num:10010
name:Wang-li
age: 19
address: 115 Beijing Road,Shanghai
Class monitor is:
num:10001
name:Li-sun
```
答案：
第1空：Student1(int n,string nam,int n1,string nam1,int a,string ad):Student(n,nam),monitor(n1,nam1)
```c++
#include
#include
using namespace std;
class Student //声明基类
{public: //公用部分
Student(int n,string nam) //基类构造函数
{num=n;
name=nam;
}
void display() //输出基类数据成员
{cout<<"num:"<
int num;
string name;
};
class Student1: public Student //用public继承方式声明派生类student
{public:
@@[Student1(int n,string nam,int n1,string nam1,int a,string ad):Student(n,nam),monitor(n1,nam1) ](2) //派生类构造函数
{age=a; //在此处只对派生类新增的数据成员初始化
addr=ad;
}
void show( )
{cout<<"This student is:"<
cout<<"age: "<
void show_monitor() //输出子对象的数据成员
{cout<
}
private: //派生类的私有数据
Student monitor; //定义子对象(班长)
int age;
string addr;
};
int main( )
{Student1 stud1(10010,"Wang-li",10001,"Li-sun",19,"115 Beijing Road,Shanghai");
stud1.show( ); //输出第一个学生的数据
stud1.show_monitor(); //输出子对象的数据
return 0;
}
```
###程序输出如下
```
This student is:
num:10010
name:Wang-li
age: 19
address: 115 Beijing Road,Shanghai
Class monitor is:
num:10001
name:Li-sun
```
答案：
第1空：Student1(int n,string nam,int n1,string nam1,int a,string ad):Student(n,nam),monitor(n1,nam1)
