I found numerical recipes in c to be pretty tricky when I started coding. It still can be unless you know the algorithms up and down (certainly with the shifted vectors/matrices...)
I always felt that there aren't strong convention in C development because everybody "says I know C" and codes in his own way - therefor you can easily get unmaintainable code.
