This book has it all. To begin with, it modestly calls itself "C: A Reference Manual". They might as well come right out with it and say "C: The Reference Manual". If you have a question about C, it will be answered here. This is not the ordinary thick and heavy tome hastily cobbled together against a deadline, but a refreshing example of old-fashioned, obstinate dedication to quality. It is lean and terse; every line carries meaning, and you will be expected to pay attention. That is not much of an exaggeration; just about every single line in the book, with the possible exception of the page numbers, is important: The examples don't just repeat the obvious; they are well chosen to point up important points, and at the end of each chapter you will find exercises that are cleverly crafted to make you cry and say "How could I have missed that!". That is also why, although the book calls itself a reference manual, it is at the same time a lesson in pedagogy. A small warning, though, just for the sake of balance: the weak point of C is also the weak point of this book, if it has one. If you are thinking of buying it just because you want an authoritative source on C declarations, this could be what you want if you have a truly superior intellect - Harbison and Steele don't miss anything, and sure enough it is all here - but most of us will need another source on that particular subject before we realize that; a more hand-holding, tear-wiping sort of source. However, in summary: I was thinking just now of whether to add the line "This is the best book ever written on any subject.", but I decided against it, as I have not read all books.
