帮忙看一下错误怎么改

[ImJaden]

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...

你这到处是书写错误啊！！！
好好检查一下你的关键词和名称

没using namespace std;还怎么编译啊

#include<iostream.h>
改成
#include<iostream>
using namespace std;

vc 6.0提供的头文件不支持运载符重载为友元函数，所以要用#include<iostream.h>
