History of C Programming Language

History:

• "Dennis Ritchie" is known as the inventor of C language.
• Dennis Ritchie developed the C in 1970's in Bell laboratories, U.S.A.
• In 1972, Ritchie started to improve B(with Ken Thompson), which resulted in creating a new language C
• He kept most of the syntax of B Language and added the new features like data types and structures.
• C was developed between 1971-1973, containing both high level and low-level functionalities which can develop applications as well as Operating system
• Initially it was designed for programming in Operating system called UNIX. But now, entire UNIX OS and tools provide by it are written in C (using low level functionalities).
• It was developed to overcome the problems of previous languages such as B, BCPL, etc. which don't understand the datatypes and structures.

Evolution of  Programming Languages:

• 1960- ALGOL(International Group)
• 1967- BCPL(Martin Richard)
• 1970- B(Ken Thompson)
• 1972/1973- Traditional C(Dennis Ritchie)
• 1978- K & RC(Kernighan & Dennis Ritchie)
• 1989- ANSI C(ANSI Committee)
• 1990- ANSI/ISO C(ISO Committee)
• 1999- C99(Standardization Committee)
