I have a problem with the assignment operator in
derived classes. Assume the following two classes:

class base 
{
  int j;
  base ()         { j=0;};
  base ( base& b) { j = b.j; }; 

  void operator = ( base &b )
    {
      if (this != &b)
        j = b.j;
    };
}

class deriv : public base 
{
  int k;
  deriv () : base()	{ k=0; }
  deriv ( deriv& d ) 
	   : base ( d )	{ k=d.k; }

  void operastor = ( deriv &d )
    {
	??????
    }
}

How can I implement the operator =?
(Probably a stupid question, but ...)

Thanks you
