C is a general-purpose, procedural, imperative computer programming language developed in 1972 by Dennis Ritchie at the Bell Telephone Laboratories for use with the UNIX operating system. C evolved from its predecessor, B.

C has since spread to many other platforms, and is now one of the most widely used programming languages. C has also greatly influenced many other popular languages, such as C++ and Objective-C, which were originally designed as enhancements to C. People are so familiar with its syntax that many other languages such as AWK, PHP, Java, JavaScript, D, and C# deliberately used its "look and feel". C is the most commonly used programming language for writing system software, though it is also widely used for writing applications. C is the lingua franca of the open source community.


  • K&R C was the first widely-used form of C. It was originally documented in The C Programming Language, published in 1978. It is named for the authors, Brian Kernighan and Dennis Ritchie (also the language's creator). Code in this style is virtually nonexistent today.
  • C89 (often called ANSI C) is the version of C standardized by ANSI in 1989. It is the most commonly used and supported version of the language.
  • C90 (often called ISO C) is identical to C89, republished by ISO in 1990.
  • C99 is a significant improvement, adopting many features of C++ and standardizing common compiler extensions. It was standardized by ISO in 1999, and by ANSI in 2000. It is primarily supported by commercial C compilers, but most of its features are available in Clang GCC. [1]
  • C11 is the current standard, published in December 2011. It is the default for GCC as of version 5.1.
