Introduction ( A Brief History of C )
सी प्रोग्रामिंग भाषा का विकास AT&T Bell Laboratory (प्रयोगशाला) USA में वर्ष 1972 में डेनिस रिची (Dennis Ritchie) द्वारा हुआ | इसकी खोज UNIX ऑपरेटिंग सिस्टम सॉफ्टवेर को बनाने में हुआ था और बाद में इसका प्रचलन अन्य कई जगह होने लगा |
ALGOL - root of all the modern languages. (early 1960s). It is the first computer language to use block structure.
1960 - Concept of block structured popularized
1967 - Martin Richards developed BCPL (Basic Combined Programming Language) - for writing system softwares
1970 - Ken Thompson created a language using many features of BCPL and called it B. It was used to create early versions of
UNIX operating system at Bell Laboratories. Both BCPL and C were typeless system programming languages.
1972 - Dennis Ritchie developed C Programming Language using many features of ALGOL, BCPL, and B. Concept of data types and many new features were added.
UNIX operating system was almost entirely coded in C.
1970 - Traditional C
1978 - "The C Programming Language" - a book by Brian Kerningham and Dennis Ritchie. It was also known as "K&R C".
1983 - ANSI (American National Standards Institute) appointed a technical committee to define standard for C.
1989 - ANSI C - standard of C
1990 - Standard of C was approved by ISO (International Standards Organization)
