Over the weekend, I was helping Norman Junior III with a C programming exercise (a wordsearch puzzle). I had rather hoped purchasing him the original and definitive text ‘Kernighan and Ritchie (Second Edition)’ would enable him to become a C wizard without any further intervention from me but no.

In a flash of inspiration, I had introduced some symbolic constants for each of the eight possible directions.

When I asked him - ‘Can you remember how to specify a constant in C ?’, he replied ‘Oh yeah - I know, I remember. Hashtag define’.
