Learning a language--any language--involves a process wherein you learn to rely less and less on instruction and more increasingly on the aspects of the language you've mastered. Whether you're learning French, Java, or C, at some point you'll set aside the tutorial and attempt to converse on your own. It's not necessary to know every subtle facet of French in order to speak it well, especially if there's a good dictionary available. Likewise, C programmers don't need to memorize every detail of C in order to write good programs. What they need instead is a reliable, comprehensive reference that they can keep nearby. C in a Nutshell is that reference.This long-awaited book is a complete reference to the C programming language and C runtime library. Its purpose is to serve as a convenient, reliable companion in your day-to-day work as a C programmer. C in a Nutshell covers virtually everything you need to program in C, describing all the elements of the language and illustrating their use with numerous examples.The book is divided into three distinct parts. The first part is a fast-paced description, reminiscent of the classic Kernighan & Ritchie text on which many C programmers cut their teeth. It focuses specifically on the C language and preprocessor directives, including extensions introduced to the ANSI standard in 1999. These topics and others are Numeric constantsImplicit and explicit type conversionsExpressions and operatorsFunctionsFixed-length and variable-length arraysPointersDynamic memory managementInput and outputThe second part of the book is a comprehensive reference to the C runtime library; it includes an overview of the contents of the standard headers and a description of each standard library function. Part III provides the necessary knowledge of the C programmer's basic the compiler, the make utility, and the debugger. The tools described here are those in the GNU software collection.C in a Nutshell is the perfect companion to K&R, and destined to be the most reached-for reference on your desk.
Look for a cow on the cover of this book. I bought this book for a C in UNIX class. The C part is great.
There is hardly a page that does not have an example or enlightening diagram. However, the only reference to applying this to UNIX is in the back where it "Practically" says that there are different versions of UNIX. It never really claimed to be a UNIX book on C. The section on unbuffered I/O has a little more on the UNIX handling of files. Overall, until something better comes along, I am still using this book.
