Hants GU14 7PL	England, U.K.Judges' comments:    This program prints out a string.  Can you figure out how    it is done?    By use of pointers to functions returning a struct of pointers     to functions!    Note that some compilers will be unable to compile the    expression 'X=g()...' in main due to lack of temporary    value space.  One might want to try replacing main with:    	main(){X=s().v().o().o().l().S().d().l().i().o().w().N();}        if this is a problem.Spoiler: (rot13 to read)    Guvf cebtenz cevagf bhg gur fgevat:    gur dhvpx oebja sbk whzcrq bire gur ynml qbt    ol hfr bs cbvagref gb shapgvbaf ergheavat n fgehpg bs cbvagref     gb shapgvbaf!Selected notes from the author: (rot13 to read)    Vg vf fvzcyr gb znxr gur cebtenz cevag bgure fgevatf.

I leave it as an intellectual exercise    to the reader to find out what it is.
