The C Programming Language by Brian W. Kernighan & Dennis M. Ritchie.

Dennis Ritchie is a legendary computer scientist who is best known for creating the C programming language and co-developing the UNIX operating system. His book, “The C Programming Language,” is considered a classic in the field and is often referred to simply as “K&R” after the authors’ initials.

First published in 1978, “The C Programming Language” was one of the first books to provide a comprehensive description of the C language. It was written by Ritchie and his colleague Brian Kernighan, who were both instrumental in the development of C and UNIX.

The book covers the fundamentals of C programming, including control flow, data types, and program structure. It also includes a detailed description of the C standard library and several examples of how to use the language to create programs.

One of the unique features of “The C Programming Language” is its concise and straightforward writing style. Ritchie and Kernighan write in a clear and concise manner, making the book easy to understand even for those with little programming experience.

Despite its age, “The C Programming Language” remains a relevant and useful resource for those learning C or looking to improve their understanding of the language. It is often used as a textbook in computer science courses and is recommended by many experienced programmers.

“The C Programming Language” by Dennis Ritchie and Brian Kernighan is a must-read for anyone interested in learning C or improving their programming skills. Its clear and concise writing style, comprehensive coverage of the language, and enduring relevance make it a classic in the field of computer science.
