C language history

History of C Programming Language

1. C is a programming language which born at “AT & T’s Bell Laboratory” of USA in 1972.
2. C was written by Dennis Ritchie, thats why he is also called as father of c programming language.
3. C language was created for a specific purpose i.e designing the UNIX operating system (which is currently base of many UNIX based OS).
4. 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
5. 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 ?

1. Many of C’s principles and ideas were derived from the earlier language B. (Ken Thompson was the developer of B Language.)
2. BCPL and CPL are the earlier ancestors of B Language
3. CPL is common Programming Language.In 1967, BCPL Language ( Basic CPL ) was created as a scaled down version of CPL
4. As many of the features were derived from “B” Language thats why it was named as “C”.
5. After 7-8 years C++ came into existence which was first example of object oriented programming .
