Help me finding the errors PLEASE !!!

HELLOW EVERY BODY

This is my program and I can't find the errors

waiting for your coments

Code:

# include <iostream>
# include <string>
# include <fstream>
# include <iomanip>

using namespace std ;

struct patient
{
string fname;
int id;
int age;
};

void Read (patient [],int&);
void Find (patient [],int,int&);
void Display (patient [],int&);

int main()
{
patient info[20];
int num(0),x(0);
 
Read(info,x);
Find(info,x,num);
cout<<"Number of patints in twenties = "<< num;
Display(info,x);
return 0;
}


void Read (patient info[],int x)
{
ifstream din;
din.open("data.dat");
int c(0);

while (din)
{
din>>info[c].fname>>info[c].id>>info[c].age;
c++;
}

}


void Find (patient info[],int x, int&num)
{
int c(0);

while (c<20)
{
if (info[c].age>20 && info[c].age<29)
num++;
c++;
}

}

void Display (patient info[],int x)
{
int c(0);
cout <<" Patint name ID";

while (c<20)
{
if (info[c].age>20 && info[c].age<29)
cout<<setw(12)<<info[c].fname<<setw(12)<<info[c].id;
c++;
}

}

Error #1: indentation sucks

I forgot to say that I am using visual stude 2005 C++

[Linker error] undefined reference to `Read(patient*, int&)'
[Linker error] undefined reference to `Display(patient*, int&)'
ld returned 1 exit status

4 errors found.

Theres something wrong with your function declarations.

I moved the main() to the end of the file and removed the

Code:

void Read (patient [],int&);
void Find (patient [],int,int&);
void Display (patient [],int&);

and the code compiled ok.

Edit: Just removing the "x" (which you aren't using anyway) from all arguments solves the problem.

Edit again: Solved it. You forgot to put & at the appropriate places in your definitions. I.e:

Code:

void Read (patient info[],int& x)
{

and

Code:

void Display (patient info[],int& x)
{
int c(0);

THANK YOU VERY MUCH
