On C programming, switch-cases and the GOSUB

The switch-statement in C and C++ is an interesting construct lending itself to many unorthodox uses. In this video I explore some of those uses. I also showcase a little BASIC program (visible from 1:16 through 1:42) that I wrote in 1993.

*) In most of my programming videos I use a custom editor I wrote myself for use in DOSBox. This video however was not created in DOSBox, but in a real Linux desktop, although a staged one for video making. My own editor only runs in DOS, so I used Joe here. Or more to the point, I don't use Joe in DOSBox, because it does not run in DOS. That's why I created my own editor. So in this video I used Joe, i.e. Joseph Allen's editor.

Addendum: In my view, lambda functions / closures target pretty much the same goal and purpose that GOSUB does, even though it is not exactly the same. I'm glad C++ has lambda functions today.

The entire source code of the dirt-dropping program (that is shown in the end of the video) is seen at 1:32.
