Operator overloading fails

[fargoth]

Hello,
I'm trying to make a very simple class, but it doesn't work, and I don't know why!

GraphPoint.h:

#ifndef _GRAPHPOINT_H
#define _GRAPHPOINT_H
class GraphPoint
{
public:
	double x,y;
	bool operator< (const & GraphPoint in_lh) const;
};
#endif 

graphpoint.cpp:

#include "GraphPoint.h"
bool GraphPoint::operator< (const & GraphPoint in_lh) const
{
	return (x < in_lh.x);
}

Now, Upon compillation I get these error:
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
(this refers to the bool return type)...
error C2146: syntax error : missing ',' before identifier 'in_lh'
error C2065: 'in_lh' : undeclared identifier
error C2228: left of '.x' must have class/struct/union

for sanity I've tried compiling this:

bool func()
{
    return true;
} 

and it compiled just fine...
Whats going on?!

missing a semicolon at the end of your class

class GraphPoint
{
  //...
};  // <- semicolon

Thanks for the quick reply...
I wrote it wrong here (will update the original post).
But my code had the semicolon...
Try again :)

It does not work even like this:

#ifndef _GRAPHPOINT_H
#define _GRAPHPOINT_H

class GraphPoint
{
public:
	double x,y;
	bool operator< (const & GraphPoint in_lh) const
	{
		return (x < in_lh.x);
	}
};

#endif 

same errors...

Because you're doing const & GraphPoint instead of const GraphPoint &
