Introduction to C


  • Computer languages can be divided into two broad categories: High Level Languages (HLL) and Low Level Languages (LLL).
  • A HLL language is easy to learn. LLL is a language that is closely related to machine or assembly languages. LLLs are generally difficult to learn. LLL are closely tied to the architecture of the host machine. A person who is familiar with one LLL will have to invest a great deal of effort in learning other.
  • C language was designed by Dennis Ritchie at Bell laboratories in the early 1970ís. The earlier version of C called B was written by Ken Thompson who adopted it from Martin Richardís BCPL (Basic Combined Programming Language). Dennis Ritchie studied BCPL, improves and named it C which is the second letter of BCPL.
  • C is a general-purpose high level language that was originally developed by Dennis Ritchie for the UNIX operating system. It was first implemented on the Digital Eqquipment Corporation PDP-11 computer in 1972.
  • The Unix operating system and virtually all Unix applications are written in the C language. C has now become a widely used professional language for various reasons.
  • Easy to learn
  • Structured language
  • It produces efficient programs.
  • It can handle low-level activities.
  • It can be compiled on a variety of computers.
  • C was invented to write an operating system called UNIX.
  • C is a successor of B language which was introduced around 1970
  • The language was formalized in 1988 by the American National Standard Institue (ANSI).
  • By 1973 UNIX OS almost totally written in C.
  • Today C is the most widely used System Programming Language.
  • Most of the state of the art software have been implemented using C

    Why to use 'C'?

    C was initially used for system development work, in particular the programs that make-up the operating system. C was adoped as a system development language because it produces code that runs nearly as fast as code written in assembly language. Some examples of the use of C might be:
  • Operating Systems
  • Language Compilers
  • Assemblers
  • Text Editors
  • Print Spoolers
  • Network Drivers
  • Modern Programs
  • Data Bases
  • Language Interpreters
  • Utilities
