Here are a couple of ways to do it:

----------------------------------------
void operator= (deriv &d)
{
  // first initialize the base class part using base::operator =
  *(base *)this = d;
  k = d.k
}
----------------------------------------

or

----------------------------------------
void operator= (deriv &d)
{
  // first initialize the base class part using base::operator =
  base::operator= (d);
  k = d.k
}
----------------------------------------

Hope that helps!
