说明：  在计算机发展的历史上，没有哪一种程序设计语言像C语言这样应用广泛。本书原著即为C语言的设计者之一Dennis M.Ritchie和著名计算机科学家Brian W.Kernighan合著的一本介绍C语言的权威经典著作。我们现在见到的大量论述C语言程序设计的教材和专著均以此书为蓝本。原著第1版中介绍的C语言成为后来广泛使用的C语言版本——标准C的基础。人们熟知的“hello,World"程序就是由本书首次引入的，现在，这一程序已经成为众多程序设计语言入门的第一课.
(In the history of computer development, no programming language is as widely used as the C language. The original work of this book is an authoritative classic on the C language, co-authored by Dennis M. Ritchie, one of the designers of the C language, and the famous computer scientist Brian W. Kernighan. A large number of textbooks and monographs on C language programming that we see now are based on this book. The C language introduced in the first edition of the original work became the basis of the widely used C language version-Standard C. The well-known "hello, World" program was first introduced in this book. Now, this program has become the first lesson of many programming languages.)
