- C is a programming language which born at “AT & T’s Bell Laboratories” of USA in 1972.
- It was written by Dennis Ritchie.
- This language was created for a specific purpose : to design the UNIX operating system (which is used on many computers).
From the beginning, C was intended to be useful to allow busy programmers to get things done because C is such a powerful, dominant and supple language, its use quickly spread beyond Bell Labs. in the late 70’s
Why Name “C” was given to Language ?
- Many of its principles and ideas were taken from the earlier language B.
- Ken Thompson was the developer of B Language.
- BCPL and CPL are the earlier ancestors of B Language
- CPL is common Programming Language.In 1967, BCPL Language ( Basic CPL ) was created as a scaled down version of CPL
- As many of the features were derived from “B” Language thats why it was named as “C”.
- After 7-8 years C++ came into existence .
