Amazon.com Review
Just about every C programmer I respect learned C from this book. Unlike many of the 1,000 page doorstops stuffed with CD-ROMs that have become popular, this volume is concise and powerful (if somewhat dangerous) -- like C itself. And it was written by Kernighan himself. Need we say more?

From the Publisher
This second editon describes C as defined by the ANSI standard. This book is meant to help the reader learn how to program in C. The book assumes some familiarity with basic programming concepts like variables, assignment statements, loops, and functions. A novice programmer should be able to read along and pick up the language.

From the Inside Flap
Preface

The computing world has undergone a revolution since the publication of The C Programming Language in 1978. Big computers are much bigger, and personal computers have capabilities that rival the mainframes of a decade ago. During this time, C has changed too, although only modestly, and it has spread far beyond its origins as the language of the UNIX operating system.

The growing popularity of C, the changes in the language over the years, and the creation of compilers by groups not involved in its design, combined to demonstrate a need for a more precise and more contemporary definition of the language than the First edition of this book provided. In 1983, the American National Standards Institute (ANSI) established a committee whose goal was to produce "an unambiguous and machine-independent definition of the language C," while still retaining its spirit. The result is the ANSI standard for C.

The standard formalizes constructions that were hinted at but not described in the first edition, particularly structure assignment and enumerations. It provides a new form of function declaration that permits cross-checking of defini-tion with use. It specifies a standard library, with an extensive set of functions for performing input and output, memory management, string manipulation, and similar tasks. It makes precise the behavior of features that were not spelled out in the original definition, and at the same time states explicitly which aspects of the language remain machine-dependent.

This second edition of The C Programming Language describes C as defined by the ANSI standard. Although we have noted the places where the language has evolved, we have chosen to write exclusively in the new form. For the most part, this makes no significant difference; the most visible change is the new form of function declaration and definition. Modern compilers already support most features of the standard.

We have tried to retain the brevity of the first edition. C is not a big language, and it is not well served by a big book. We have improved the exposition of critical features, such as pointers, that are central to C programming. We have refined the original examples, and have added new examples in several chapters. For instance, the treatment of complicated declarations is augmented by programs that convert declarations into words and vice versa. As before, all examples have been tested directly from the text, which is in machine-readable form.

Appendix A, the reference manual, is not the standard, but our attempt to convey the essentials of the standard in a smaller space. It is meant for easy comprehension by programmers, but not as a definition for compiler writersÑ that role properly belongs to the standard itself. Appendix B is a summary of the facilities of the standard library. It too is meant for reference by programmers, not implementers. Appendix C is a concise summary of the changes from the original version.

As we said in the preface to the first edition, C "wears well as one's experience with it grows." With a decade more experience, we still feel that way. We hope that this book will help you to learn C and to use it well.Brian W. Kernighan, Dennis M. RitchiePreface to the First Edition

C is a general-purpose programming language which features economy of expression, modern control flow and data structures, and a rich set of operators. C is not a "very high level" language, nor a "big" one, and is not specialized to any particular area of application. But its absence of restrictions and its generality make it more convenient and effective for many tasks than

supposedly more powerful languages.

C was originally designed for and implemented on the UNIX operating sys-tem on the DEC PDP-1 1, by Dennis Ritchie. The operating system, the C compiler, and essentially all UNIX applications programs (including all of the software used to prepare this book) are written in C. Production compilers also exist for several other machines, including the IBM System/370, the Honeywell 6000, and the Interdata 8/32. C is not tied to any particular hardware or system, however, and it is easy to write programs that will run without change on any machine that supports C.

This book is meant to help the reader learn how to program in C. It contains a tutorial introduction to get new users started as soon as possible, separate chapters on each major feature, and a reference manual. Most of the treatment is based on reading, writing and revising examples, rather than on mere statements of rules. For the most part, the examples are complete, real programs, rather than isolated fragments. All examples have been tested directly from the text, which is in machine-readable form. Besides showing how to make

effective use of the language, we have also tried where possible to illustrate useful

algorithms and principles of good style and sound design.

The book is not an introductory programming manual; it assumes some familiarity with basic programming concepts like variables, assignment statements, loops, and functions. Nonetheless, a novice programmer should be able to read along and pick up the language, although access to a more knowledgeable colleague will help.

In our experience, C has proven to be a pleasant, expressive, and versatile language for a wide variety of programs. It is easy to learn, and it wears well as one's experience with it grows. We hope that this book will help you to use it well.Brian W. Kernighan, Dennis M. Ritchie

A high-intensity tutorial and a great reference
This book (widely known as K&R, after the authors' initials) has for over twenty years been the best way to learn C. When I got this book in 1980, I had access to a Unix system and worked through much of the tutorial material in it. On the way I learnt a great deal, not just about C, but about good programming style, code reuse, the value of clear comments--in short, I was introduced to the skill set of an experienced computer professional.

The book was a trendsetter in several ways. For example, the very first exercise given is to print "hello, world"; this is now seen as the first exercise in innumerable other, more recent books, many of which may not realize that they are borrowing from K&R. The rest of chapter 1 (there's a chapter 0, an introduction; another geek-cool change which has been widely copied) is a tutorial that takes you through assignment statements, data types, if/else, for, while, printf, function definitions, arrays, and variable scoping, in less than 30 pages. If you work your way through the embedded exercises you'll have written utilities to strip tabs, reverse input by lines, strip trailing whitespace from input, and several others. This is much more challenging than most tutorials, but the effect on the student is that you feel you are being treated as an equal. The book doesn't talk down to you; it gives you accurate and concise answers. It's written for programmers, in other words.

The next few chapters go back over the elements of C in more detail, and should also be treated as a tutorial. Going through this material religiously will be far more valuable than any college class could possibly be.

There is a reference section at the back, which is good to have. But the real value of this book is in the tutorial approach: it is a rare pleasure in the computing field to find a book that is simultaneously clear, stimulating and informative.

The best programming book I ever bought.
I've first bought this book when I started my academic studies,and 5 years of work with Fortran 77 and three years of work withPascal.

This small book (270 pages, including the index) served me well through my degree, and I still keep the dog-eared, yellowing, aged book with me at work.

The book focuses on the language itself - this is no hands-on book (no explanations on how to use this compiler or that debugger, though it is a little biased toward Unix) in a clear, concise, and thorough way covering all of the language and it's standard libraries.

I especially liked the excercises (the solutions come in a seperate volume) and the C source code examples of how some of the library routines are (or may be) implemented.

With this book I had no problem understanding the more difficult subjects (e.g. many people have problems with pointers, and this book makes the subject easy to understand) and avoiding pitfalls.

I've read it in a week, and keeping it in hand's reach smoothly started programming in C.

The only drawback I see in this book is it's price, it's a small book which sells *very* well, and I'd expect it's price to be lower. This book is *not* for people who study C as their first programming language (those would be better served with a pair of books - a first course in programming and compiler guide).

The most elegant programming book I have ever read
This book is not "for Dummies". It assumes that you already have some knowledge of structured programming languages (i.e. Pascal). For example, this book spends four well-written pages explaining everything you need to know about functions. If you don't know what a function is, this will clearly not be enough. However, if you do know about functions, this book will not drone on and on for an entire chapter or two on the subject like some of the foot-crunching tomes the size of an encyclopdia.

The book is expensive ($40) for its size (approx. 250pgs.), but it is worth every penny. To quote the authors: "C is not a big language, and it is not served well by a big book."

As a bonus, almost anything you need to know about C can be found in seconds using the excellent index. It should be noted that this is a language reference and will NOT tell you how to use your editing environment or compiler.

In summary, intermediate or advanced programmers should be able to learn C with reasonable proficiency in a short amount of time.
