History of C Programming Language
C is a programming language which born at “AT & T’s Bell Laboratory” of USA in 1972.
C was written by Dennis Ritchie, thats why he is also called as father of c programming language.
C language was created for a specific purpose i.e designing the UNIX operating system (which is currently base of many UNIX based OS).
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 because of its long list of strong features
Why Name “C” was given to Language ?
Many of C’s principles and ideas were derived 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 which was first example of object oriented programming .
