#include<iostream>

using namespace std;
class phonebook
{
char name[20];
int areacode;
int perfix;
int num;
public:
phonebook(char *n,int a,int p,int nm)
{
strcpy(name,n);
areacode=a;
perfix=p;
num=nm;
}
friend ostream &operator<<(ostream &stream,phonebook o) ;
};
ostream &operator<<(ostream &stream,phonebook o)
{
stream<<o.name<<" ";
stream<<"("<<o.areacode<<")"<<endl;
stream<<o.perfix<<"-"<<o.num<<endl;
return stream;
}
void main()
{
phonebook a("Ted",111,555,1234);
cout<<a;
}
问题描述：这个是我抄书的，重载<<作为类的友元函数写在了类成员函数里，但在编译时出现不能访问私友成员的提示如下：

请帮我看一下是那个地方出现了问题，谢了啊
