您好，以下代码是关于C++问题#include <iostream>的，请问该怎么办？
#include <string>
using namespace std;
class date
{
private:
int year ;
int month;
int day;
public :
date()
{
cout<<"构造函数";
};
void setDate(int y ,int m ,int d )
{
year=y;
month=m;
day=d;
};
date (date&bir)
{
year =bir.year ;
month=bir.month;
day=bir.day;
};
int getYear()
{
return year;
};
int getMonth()
{
return month;
};
int getDay()
{
return day;
};
};
class people
{
private:
date birthday;
int num;
char name[20];
char sex[4];
char id[20];
public :
people()
{
};
void input()
{
int y,m,d;
cout<<"录入数据";
cout<<"编号"<<endl;
cin>>num;
cout<<"姓名"<<endl;
cin>>name;
cout<<"性别"<<endl;
cin>>sex; //40
cout<<"身份证编号"<<endl;
cin>>id;
cout<<"出生日期(年月日)"<<endl;
cin>>y>>m>>d;
birthday.setDate(y,m,d);
};
void output()
{
cout<<"编号"<<num<<endl;
cout<<"姓名"<<name<<endl;
cout<<"性别"<<sex<<endl ;
cout<<"身份证编号"<<id<<endl;
cout<<"生日"<<birthday;
};
};
int main()
{
people p1;
p1.input();
p1.output();
return 0;
}
最后在output()方法里面输出birthday报错，该怎样修改？
本人C++小白，问下复制函数到底有什么用？以上面为例，把那个的复制函数去掉可否？

#include <iostream>//要加上这个头文件#include <string> using namespace std; class date{private: int year ; int month; int day; public : date() { cout<<"构造函数"; }; void setDate(int y ,int m ,int d ) { year=y; month=m; day=d; }; date (date&bir) { year =bir.year ; month=bir.month; day=bir.day; }; int getYear() { return year; }; int getMonth() { return month;}; int getDay() { return day; }; void out() { cout<<"年:"<<getYear()<<" 月"<<getMonth()<<" 日"<<getDay()<<endl; }//加个输出函数};class people{private: date birthday; int num; char name[20]; char sex[4]; char id[20]; public : people() { }; void input() { int y,m,d; cout<<"录入数据"; cout<<"编号"<<endl; cin>>num; cout<<"姓名"<<endl; cin>>name; cout<<"性别"<<endl; cin>>sex; cout<<"身份证编号"<<endl; cin>>id; cout<<"出生日期(年月日)"<<endl; cin>>y>>m>>d; birthday.setDate(y,m,d); }; void output() { cout<<"编号"<<num<<endl; cout<<"姓名"<<name<<endl; cout<<"性别"<<sex<<endl ; cout<<"身份证编号"<<id<<endl; //cout<<"生日"<<birthday; birthday.out();//调用输出函数}; }; int main() { people p1; p1.input(); p1.output(); return 0;}//楼下的已经说了为什么错了，如果真要输出cout<<birthday就要用重载输入输出流 -
噜噜哒
1给cout输出流添加类。2.《深度探索C++对象模型》《C++沉思录》两本书精解。3，函数体后可不加分号，但类体大括号外必须加分号。#include <string> #include<iostream>using namespace std;class date {private: int year; int month; int day;public: date() { cout << "构造函数"; } void setDate(int y, int m, int d) { year = y; month = m; day = d; } date(date&bir) { year = bir.year; month = bir.month; day = bir.day; } int getYear() { return year; } int getMonth() { return month; } int getDay() { return day; }friend ostream& operator<<(ostream&,date& d);};ostream& operator<<(ostream& os,date& d){ return os<<d.year<<'/'<<d.month<<'/'<<d.day<<endl; }class people {private: date birthday; int num; char name[20]; char sex[4]; char id[20]; public: people() { } void input() { int y, m, d; cout << "录入数据"; cout << "编号" << endl; cin >> num; cout << "姓名" << endl; cin >> name; cout << "性别" << endl; cin >> sex; //40 cout << "身份证编号" << endl; cin >> id; cout << "出生日期(年月日)" << endl; cin >> y >> m >> d; birthday.setDate(y, m, d); } void output() { cout << "编号" << num << endl; cout << "姓名" << name << endl; cout << "性别" << sex << endl; cout << "身份证编号" << id << endl; cout << "生日" <<birthday <<endl;//; }}; int main() { people p1; p1.input(); p1.output(); return 0;}
