You don't need the inner inclusion guards, the outer per-file ones are
sufficient.

To Tom:
As others have said, don't use "this".  In the same vein don't use
"private" or "public" either.

Your approach is a typical implementation of OOP in C, not something
"by the backdoor" (heck, the first C++ compiler - CFront - compiled
C++ into C).

Perhaps a more valuable answer would go along the lines of "a good
intro book to C is ...." although its been so long since I trod that
path that I can't personally recommend any introductory books myself,
although I can recommend Harbison and Steele as a good read.
