Sorry, that I have no fun with it :-(

I have only fun with code, where was a trick inside, e.g. some clever algorithm or solve something more efficient (size or speed) as usual.
But hiding a needle in a haystack was no trick on my view.


Also I looked more on your first post: "...learning C coding...". But I disagree, awkward and confused code was a not good point to start with C.
Thus I would clearly state, that it can only teach as a negative example, what should be avoided on real programs.
