Hi there!

I keep getting an error stating error: expected unqualified-id before 'bool' when I try to compile this file

#include "Data.h"
#include <iostream>


Data::Data(char aLetter, int anOrder)


ostream& operator<< (ostream& out,const Data& someData)  
	out << "(" << someData.order << ", " <<  
	someData.letter << ")";  
	return out;  

Data::bool operator<(Data& someData)
	return this->order<someData.order;
#ifndef Data_H_include
#define	DATA_H_include
#include <iostream>

using namespace std;

class Data
		int order;
		char letter;


		Data(char, int);
	bool operator<(const Data&) const;

	friend ostream& operator<<(ostream&,const Data&);

I'm getting fairly frustrated as I am not sure what to put before bool. Can anyone help me?

Been a while since I've used that syntax, but I think it is supposed to be:

bool Data::operator

Compare bool operator<(const Data&) const; in the class definition and operator<(Data& someData) in the member function implementation.
And correct this awful Data::bool operator<(Data& someData) to

bool Data::operator<(const Data& ...

actually the first one is correct. LOL, I found out on the 1001th try
