请问高手们运行这个程序时出现missing function header (old-style formal list?)这个错误怎么解决啊？

[失败是妈妈]

#include<iostream.h>
#include<string.h>
//#include<stdio.h>
class date
{
private:
int year;
int month;
int day;
public:
date(int a, int b, int c);
void born(void);
};
class people
{
private:
char name[6];
char sex[2];
date birthday;
public:
people( char*, char*, int, int, int);
void printf(void);
};
date::date(int a,int b,int c)
{ year=a;
month=b;
day=c;
}
void date::born(void)
{
cout<<year<<month<<day;
}
people::people(char* d, char* h,int a,int b,int c);
birthday(int a,int b,int c);
{ strcpy (name,d);
strcpy (sex,h);

}
void people::printf(void)
{
cout<<name;
cout<<sex;
birthday.born();
}
void main()
{
int a,b,c;
char d[6], h[2];
cout<<"姓名";
cin>>d;
cout<<"性别";
cin>>h;
cout<<"年";
cin>>a;
cout<<"month";
cin>>b;
cout<<"day";
cin>>c;

people sl(d,h,a,b,c);
sl.printf();


}

[fuzb]

people::people(char* d, char* h,int a,int b,int c);
birthday(int a,int b,int c);
{
strcpy (name,d);
strcpy (sex,h);

}
你这个写法是错误的吧，我象你是想用d,h,a,b,c这几个参数对name,sex,birthday初始化，应该写成：
people::people(char* d, char* h,int a,int b,int c)： //；改成:
birthday(a,b,c) //birthday(int a,int b,int c)改为birthday(a,b,c)
{
strcpy (name,d);
strcpy (sex,h);

}

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

[fallhunter]

people::people(char* d, char* h,int a,int b,int c);
birthday(int a,int b,int c);
{
strcpy (name,d);
strcpy (sex,h);

}
改成：
people::people(char* d, char* h,int a,int b,int c):birthday(a,b,c)

[zxl_llx]

people::people(char* d, char* h,int a,int b,int c);//<---------改成：
birthday(int a,int b,int c);//<-----------------改成birthday(a,b,c);
{ strcpy (name,d);
strcpy (sex,h);

}

[fallhunter]

birthday(a,b,c)是对成员调用构造函数

可以揭帖了～～

这么快啊！
