wierd error message

Hi there everyone I'm trying to output an array to a text file but for some reason I keep getting an error message. Would anyone have any advice

Code:

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

using namespace std;

class packunpack
{
private:
	char lname[15];
	char fname[15];
	char email[36];
	char stuid[15];
	char buffer[65];
	ofstream outfile("fixlength.txt");
public:
friend ostream& operator <<(ostream &stream, packunpack &p)
{ 
	output<<p.buffer<<endl;
	
	return stream;
}
	 
friend istream& operator >>(istream &stream, packunpack &p)
	{
	
	char buffer[60];
	char fixlng[5]={"    "};
	
	stream.getline(p.lname, 15, '\n');
	strcpy(buffer, p.lname);
	strcat(buffer, fixlng);
	
	stream.getline(p.fname, 15, '\n');
	strcat(p.buffer, p.fname);
	strcat(p.buffer, fixlng);
	
	stream.getline(p.stuid, 15, '\n');
	strcat(p.buffer, p.stuid);
	strcat(p.buffer, fixlng);

	stream.getline(p.email, 35);
	strcat(p.buffer, p.email);
    strcat(p.buffer, fixlng);
	
	cout << p;
    
	return stream;
	}
};
 
void main()
{
	
	packunpack t;
	fstream infile;
	infile.open("f.txt", ios::in);
	
	while(!infile.eof())
	{
	infile >> t;
	}
    infile.close();
}

Anyone have any idea whats going wrong here. I get error message
error C2059 it says 'string' and that is it

Well, knowing the error msg would make things simpler

> ofstream outfile("fixlength.txt");
My guess is it doesn't like instance information in a class declaration.

> void main
And everyone should object to this!
