    So I have a class with a > operator overloaded method. Its to use it with the priority_queue.
    if I do:
    bool operator>( const X& x0 )
    { return ( y > x0.y ); }
    it gives me a compiling error, something like, no operator which takes a left hand object.
    If I do
    bool operator>( const X& x0, const X& x1 )
    { return ( x0.y > x1.y ); }
    It says operator> has too many parameters.
    Any suggestions?

    I fixed it. But now its faulting when I try to push a second item.

    I think you're going to have to post a bit more code.

    A typical relational overload look like this...

    Code:
    bool Class::operator>(Class Obj)
    {
        if ( some test on Obj )
        {
            return true;
        }
        else
        {
            return false;
        }
    }
    Wave upon wave of demented avengers march cheerfully out of obscurity unto the dream.

    have you declared the second one as a friend function? then it takes 2 arguments, otherwise it'll need to be a member function where you can use the this pointer
