Query: incredibly bad book

this book is not only for beginners, but also written BY an absolute beginner. as an example, on page 28: "The hexadecimal number system is sometimes used in advanced C programming to reference concise memory addresses, such as during system-level programming". Hmmm, 'concise' addresses... 'during' system level programming, 'sometimes'. the example table then lists FFF4, FHH6 and FHF2 as examples of hex addresses. yes, FHH6, and FHF2 in the author's opinion are hex numbers. and so on.
