Query: Incomprehensible

DO NOT BUY THIS BOOK!!!.It is very poorly written. It is almost incomprehensible. The author simply does not know how to explain. All too often the topic of each paragraph is not made clear or presented until its conclusion if then. All too often I have had to re-read paragraphs numerous times attempting to make some sense of what I just read even then often failing. It is as if it is written in a foreign language. Even recalling the effort made in those attempts as I write this is unpleasant. He also presents quite a bit of material which discusses design rather then the language proper also in the same almost incomprehensible manner. Once again:DO NOT BUY HIS BOOK!!! To see how a language book SHOULD be written see "C: A Reference Manual" by Harbison and Steele.
