这个代码 显示第五行有问题 哪里有问题呢

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

main函数只能有一个，你类上边那个可以删掉

第三行 int main()去掉
你的c++基础比较差，不要着急写代码，先看基础的书啊
