History of C-Programming

      From the very first efforts for developing a general purpose languages. In late 1960's, when several languages came into existence like FORTRAN, COBAL, ALGOL,etc. non of them came up to be soul powerful, user-friendly language. In 1963, Cambridge University came up with another language CPL(Combined Programming Language) which was too large and vague enough to be used and to understand.
     Later on, Martin Richards (Cambridge University) in 1967, developed BCPL, but was found to be very specific and less powerful.
    Finally, in 1970, Ken Thompson (developer of UNIX) AT&T Bell lab, develop programming language 'B' to rewrite UNIX, but was unsuccessful due to its weakness in lack of instruction.
    Then in 1972, en-covering every good aspects of BCPL,CPL and B languages, Dennis Ritchie(AT &T Bell lab) developed 'C' language which provides efficient translator for machine codes. Thompson and Ritchie re-wrote UNIX in 'C'.
     By the mid 1980's, the popularity of 'C' language become wide spread and several version came into existence. Consequently, ANSI(American National Standard Institute) decided to develop standard version in 1983 and also forms a committee of computer experts. The committee approve the version of 'C' in 1989 which is now known as ANSIC. It was then approve by ISO(International Standard Organisation).
