Thanx for the reply.
If by dereferencing the pointer you mean
for_each(shapes.begin(), shapes.end(), bind(&shape::draw, *_1, 2));
then I get another error - cannot instantiate abstract class.
Yeah. I fixed this yesterday. There's also a possibility that
&*_1 will work.
Plus I would expect the dereferencing to slice off the derived bits of
circle and rectangle.
It won't, because the objects will be passed by reference.
