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
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

This book is certainly not for beginners, though not a requirements but at least the reader should have a background on Data Structure in order to easily follow most of the examples. The book was also structured to re-use the functions built from previous chapters like getline, atof, strcmp, alloc, etc.., though some of these functions have an equivalent in C's standard library, the authors choose to re-use it.
If you pay attention to the details on this book, you will pick-up the most important area of C that will save you from scratching your head while debugging your code like side effects of infix/postfix increments, precedence of statement evaluation etc..
The authors also discussed some of the best practices in order to optimize the use of language such as efficient manipulation of pointers, style on delaring variables and initializations. Some of the coding style of this book was also used by coding guidelines found in official website of linux kernel.
This book is commendable not only because it was written by the Kernihan and the creator of the language itself(Richie) but how the book was organized and well explained. This is a small book with big information.

It doesn't get much better than this
I'm not new to programming; in fact I've been doing it professionally for the past decade. Although I've played around in quite a few different languages, most of my work over the last 6 years has been in .NET (C# mainly). I have always had an interest in C because I love its simplicity. Also, it's a language which brings one closer to the machine, stripping away many of the abstractions that higher level languages provide. Higher level languages (such as Java, C#, Python, etc.) are massive and powerful with HUGE frameworks, but I'm attracted to simple things.
This book is a feisty little devil! I had heard of this book before diving in (it is a classic), but its size and table of contents lead me to believe I would breeze right through it. Wrong! Picking up the syntax wasn't too difficult and I have a fairly good handle on more advanced concepts like pointers already, but this book is absolutely packed with exercises and many of them are quite challenging!
"Write a program to check a C program for syntax errors like unbalanced parenthesis, brackets and braces. Don't forget about quotes, both single and double, escape sequences, and comments."
This is a chapter 1 exercise! Chapter 1 is just a tutorial introduction chapter and this is one 1 of 24 exercises in this chapter! No wonder it takes people years to work through this tiny book. I'm only about halfway through as I write this review.
This book is the perfect blend of reference material, practical knowledge and challenging exercises. There is absolutely no fluff and not a single word is wasted. I grow tired of pouring through 1,000+ page tomes. The appendices are also very well structured and extremely helpful.
Although I do virtually no C coding professionally, I can say for certain that this book has leveled up my skill-set. Working through these exercises has helped me with logical thinking and having a better understanding of coding closer to the machine has improved me as a developer overall. I'm one who believes that this book is great for all programmers, even if you never write a line of C after working through this book. I'm really loving the C language!
Whether you are a beginner or experienced it's worth having this book. Though this will be quite tough for total beginners, I say it's still work picking up and pairing it with a more beginner-friendly book. Unfortunately I cannot recommend such a book at this time because this is the only C book I've worked through.

The C programming language is such a clean, condense ...
By Aaron Batilo
The C programming language is such a clean, condense, and focused book on exactly what you want to learn: the C programming language. In the beginning of the book they even explicitly tell you how they aren't there to try and teach you the fluff, or writing clean code. The book is there to teach you about one of the most important languages of our modern world. This book is a must have for any developer who wants to take their personal advancement seriously. Even if you don't use C in your daily job or life, I personally believe you should still learn it and use this exact book because nobody can explain it more clearly than the creators of the language.
