C was developed in the early 1970s by Dennis Ritchie at Bell Labs as an evolution of ALGOL, BCPL, and B programming languages. It became widely popular after the publication of "The C Programming Language" book in 1978. C was later standardized as ANSI C in 1989 and ISO/IEC 9899 in 1990. The language continued to evolve with extensions and refinements such as C99. C remains one of the most widely used programming languages due to its portability and role in developing operating systems like UNIX.

History Of C
What is C ? C is a high-level and general purpose programming language that is ideal for developing firmware or portable applications. C is what is called a compiled language.
History Of C ALGOL o The root of all modern languages is ALGOL Introduced in the early 1960s. o ALGOL was the first computer language to use a block structure. o ALGOL gave the concept of structured programming to the computer science. Peter Naur
History Of C BCPL o In 1967, Martin Richards developed a language called (Basic Combined Programming Language). o In 1970, Ken Thompson created a language using many features of BCPL and called it simply B. o Both BCPL and B were “typeless” system programming languages. Martin Richards Ken Thompson
History Of C  In 1972 C was evolved from ALGOL, BCPL and B by Dennis Ritchie at the Bell Laboratories.  C uses many concepts from theses languages and added the concept of data types and other powerful features.  It is strongly associated with UNIX.  UNIX is one of the most popular network operating systems in use today.
History Of C Traditional C o During 1970s C had evolved into what is now known as “traditional C”. o The language became more popular after publication of the book ‘The C programming language’ by Brian Kerningham and Dennis Ritchie in 1978. o For many years, C was used mainly in academic environments. o Today , C is running under a variety of operating system and hardware platforms.
History Of C Brian Kerningham Dennis Ritchie o The Book was so popular that the language came to be known as “K&R C” among the programming community.
History Of C ANSI C o In 1983 American National Standards Institute (ANSI) appointed a technical committee to define a standard for C. o In December 1989 the committee approved a version of C which is known as ANSI C. o It was then approved by the International Standards Organization (ISO) in 1990. o This version of C is also referred to as C89.
History Of C ANSI/ISO C o During 1990s, C++, a language entirely based on C, underwent a number of improvements and became an ANSI/ISO approved language in November 1977. o C++ added several new features to C to make it only a true object- oriented language but also a more versatile language. o During the same period, Sun Microsystems of USA created a new language java modelled on C and C++.
History Of C C99 o C99 (previously known as C9X) is an informal name for ISO/IEC 9899: 1999. o It extends the previous version (C90) with new features for the language and the standard library. o C99 is, for the most part, backward compatible with C89, but it is stricter in some ways.
History Of C 1960 1967 1970 1972 1978 1989 1990 1999 ALGOL BCPL B Traditional C K&R C ANSI C ANSI/ISO C C99
THE END
