Don't even say that! (though, on XBox, it might even work decently) ;)

Parsers are cool - did I mention AI? ;D  One of the older, but more fun, areas of AI is natural language parsing.  When you go past, say, computer language parsing - where you have a very strict set of rules and grammars - things get interesting... let's say.  Since natural languages don't conform to 'strict rules', the parser has to be very flexible (a recursive descent parser doesn't always work very well).  The grammars have to be flexible ("this is it", "it is this", "this it is" are ALL valid for an extremely simplistic English grammatical case).  Codifying something like English for NLP is nothing to scoff at - PhDs in AI have spent decades on this problem.  While strides have been made, any application that purports to 'understand what you say' always teases a giggle out of me... 8)

Some problems are hard... some are NP hard.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
