Introduction to C Language
C is a general-purpose programming language developed by Dennis Ritchie at AT&T
Bell Laboratories of the USA in 1972. It was named 'C' because many of its features were
derived from an earlier language called 'B', which according to Ken Thompson was
evolved from BCPL (Basic Combined Programming Language). In 1988 ANSI (American
National Standards Institute) adopted a new and improved version of C, which is
known as ANSI-C. The language C was developed to rewrite the UNIX operating
system. Today, most of the programs that run under UNIX are written in C.
