我没有按书上的原意写的，还是重载了输出，可提示的错误我不知道怎么改。

#include<iostream.h>
class Student1
{
public:
void get_value()
{
cin>>num>>name>>sex;
}
friend ostream& operator<<(ostream &out,Student1 &stud)
{
out<<"number:/n"<<stud.num<<"name:/n"<<stud.name<<"sex:/n"<<stud.sex<<endl;
return out;
}
private:
int num;
char name[20];
char sex;
};
/*ostream& operator<<(ostream &out,Student1 &stud)
{
out<<"number:/n"<<stud.num<<"name:/n"<<stud.name<<"sex:/n"<<stud.sex<<endl;
return out;
}*/

class Student2:public Student1
{
public:
void get_value_1()
{
  get_value();
  cin>>age>>addr;
  cout<<endl;
}
friend ostream& operator<<(ostream&,Student2)
{
out<<"age:/n"<<stud.age<<"addr:/n"<<stud.addr;
   return out;
}
protect:
int age;
char addr[30];
};
/*ostream& operator<<(ostream &out,Student2 &stud)
{
out<<"age:/n"<<stud.age<<"addr:/n"<<stud.addr;
return out;
}*/
int main()
{
Student2 stud;
cout<<"input the Student's number,name,sex,age,addr:/n";
stud.get_value_1();
cout<<stud;
return 0;
}
Compiling...
