C program

'C' is one of the most popular programming language, it was developed by Dennis Ritchie at AT & T's Bell Laboratories at USA in 1972. It is an upgraded version of two earlier languages, called BCPL and B, which were also developed at Bell laboratories.

   The root map for all modern computer languages are started through the ALGOL language, in early 1960's after then COBOL was being used for commercial applications, FORTRAN was being developed for scientific Applications, At this stage, people started thinking  about the single language which can program all possible applications. A committee was formed to develop a new language called Combined Programming Language (CPL) at Cambridge University. It seemed to abstract too general another language called Basic Combined Programming Language (BCPL) was developed by Martin Richards at Cambridge University with some additional features than CPL.

   At the same time, a language called 'B' was developed by Ken Thompson at AT & T's Bell labs. But like BCPL and B turned out to be very specific, Dennis Ritchie developed a language with some additional features of BCPL and B which is very simple, relatively good programming efficiency and a relatively good machine efficiency called 'C' language, consequently the ANSI (American National Standard Institute) has began to work on a standardised definition of the 'C' language this make it still powerful.
