Compiling a multpile file project.

Hey everyone, I'm using Dev-C++ to write a barebones image processor for my Data structures class and I'm having trouble combining all of my files.

From Driver.cpp

#include <iostream>

#include <cmath>
#include "image.h"

using namespace std;

#ifndef IMAGE_H
#define IMAGE_H


using namespace std;

// a simple example - you would need to add more funtions

class ImageType {
 public:
   // functions irrelevant to the problem
   void negateImage(/*stub*/);
   ImageType& operator+(&ImageType);/*stub*/
   ImageType& operator-(&ImageType);/*stub*/
   ImageType& operator=(&ImageType);/*stub*/


image.cpp

//#include <stdlib.h>
//#include <stdio.h>
#include "image.h"

using namespace std;



Some of the #includes are commented out because I thought perhaps I had done something wrong, but nothing I tried seemed to help.

These is the compiler error I'm getting:

ISO C++ forbids declaration of `ImageType' with no type
expected `;' before '&' token

I get that one for all three of the overloaded operators.

So, how exactly to I manage all the #includes so that Dev-C++ will be able to compile my files correctly? Or is there something else going on?

when making references, the & comes after the typename. Just like your return type.

Also, your + and - operators probably shouldn't be returning a reference.

And you should also probably make this const correct while you're at it:

class ImageType {
 public:
   // functions irrelevant to the problem
   void negateImage(/*stub*/);
   ImageType operator+(const ImageType&) const; // const correct, doesn't return a reference
   ImageType operator-(const ImageType&) const; // ditto
   ImageType& operator=(const ImageType&); // this should return a reference

That was a rookie mistake on my part, but I'm still getting the "ISO C++ forbids declaration of `ImageType' with no type" error. Is there something wrong with the class specification?

what line is giving you that error?

Are you making sure to finish the class with a };?
