Answer 1

你怎么输入的呢，可能是你的输入有问题。

代码：

#include <iostream>
using namespace std;
class Student
{
private :
    int num;
    int score;
public:
    void setdata()
    {cin>>num;
    cin>>score;
    }
    void display()
    {cout<<"num="<<num<<endl;
    cout<<"score="<<score<<endl;
    };
} ;
Student stud1,stud2;
int main()
{
    stud1.setdata();
    stud2.setdata();
    stud1.display();
    stud2.display();
    return 0;

}
