LLM-generated summary
Kernighan and Ritchie’s The C Programming Language is the classic, compact introduction to C by the language’s authors, covering types, control flow, functions, pointers, arrays, structures, and the standard library in a spare, example-driven style. This 1988 second edition teaches ANSI C and remains a model of how to present a systems language without padding. It is both a tutorial and a short reference for writing idiomatic C.
