第11周 代码填充-是春哥啊

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: 春哥

Grade: 19

#include <iostream>
#include <cstring>
using namespace std;
class Person{
public:
    Person(char* s){
        strcpy(name,s);
    }
    void display( ){
        cout<<"Name: "<<name<<endl;
    }
private:
    char name [20];
};
class Student: ___________//(1)
{
public:
    Student(char* s, int g):__________ // (2)
    {grade=g;}
    void display1( ) {
        _________;   //  (3)
        cout<<"Grade: "<<grade<<endl;
    }
private:
    int grade;
};
int main( )
{
    Student s("春哥",19);
    ___________;       //  (4)
    return 0;
}

代码：

#include <iostream>
#include <cstring>
using namespace std;
class Person{
public:
    Person(char* s){
        strcpy(name,s);
    }
    void display( ){
        cout<<"Name: "<<name<<endl;
    }
private:
    char name [20];
};
class Student: public Person//(1)
{
public:
    Student(char* s, int g):Person(s) // (2)
    {grade=g;}
    void display1( ) {
        display();   //  (3)
        cout<<"Grade: "<<grade<<endl;
    }
private:
    int grade;
};
int main( )
{
    Student s("春哥",19);
    s.display1();       //  (4)
    return 0;
}

运行结果：
