Why you should never have to call super.Foo() in an Foo overload.

This is a classic example of poorly structured points of customisation.

For example, when you have:

class Base
{

virtual void Foo();

-- A five digit number minus a four digit number equals 33333,
-- where the nine contributing digits are 1-9, each used only once.

Landcap is a Fractal Landscape Generator for DOS/VGA PC's, that I wrote when I was in college, circa 1993. It was originally released as shareware, and got 1 (one) £10 registration for my efforts. It was reviewed in PC-Format magazine in the same issue as Alta-Vista, which was/is a much better commercial application that does the same thing. At …
