C is a general-purpose language. It is called C because it was an improvement over another language called B that was developed at AT&T Bell Labs in the early 1970s. C was developed by Brian Keminghan and Dennis Ritchie. It is closely associated with the UNIX system since the C language was developed on UNIX. Although UNIX was initially written in assembly language, Dennis Ritchie later rewrote UNIX in C language. In a short time C has become an extremely popular language and is now widely used in system development applications and for commercial uses. C is a concise language that provides a high level of modularity.
