c++第8题

#include <iostream>

using namespace std;

class Student

{

public:

Student(int n,float s):num(n),score(s){}//构造函数

void change(int n,floats){num=n;score=s;}//类赋值

voiddisplay(){cout<<num<<" "<<score<<endl;}// 显示函数和分数分离blackspace买下

 private:

       intnum;

float score;

};

void fun(Student &s)

{

s.display();

s.change(101,80.5);

s.display();

}

int main()

{

void fun(Student&);

Student stud(101,78.5);

fun(stud);

return 0;

}
