History of C Language [ A Brief History of C ]
The history of C Programming Language is very interesting, here I am going to tell you the
history of C Language, which most of you will not know.
So, friends read this post till the end, so that you will get complete information about the
history of C language and you will not have to search about it anywhere else.
History of C Language
What is the History of C Language?
In earlier times, every programming language was created to fulfill some purpose, such as
Forton (Formula Translator) was created to make Scientific and Mathematical Applications.
Similarly, COBOL (Common Business Oriented Language) was created to make business
applications.
In a similar way, C Language was also originally created to make the Unix operating system.
C Language was developed by Dennis Ritchie in 1972 at Bell Laboratories of AT&T (American
Telephone & Telegraph).
Dennis Ritchie is said to be the inventor of the C language, but the history of C language is
quite interesting.
In 1960 Dennis Ritchie and some other employees working on a project called Multics, at
Bell Laboratories of AT&T (American Telephone & Telegraph).
The aim of this project was to create an operating system for a large computer on which
thousands of people could work simultaneously.
But AT&T Bell Laboratories closed this project after a few years because this project could
not make money for them. After the closure of the project, all the employees of this project
got involved in the work of another project.
Ken Thompson, who was also working on Project Multics, created a file system. He used the
knowledge gained from the Multics project to further improve this file system.
When Ken Thompson completed the work of that system, he named the system Unix, the
entire code of this system was written in Assembly Language.
Ken Thompson created Unix with the help of B Language, B Language was created by Ken
Thompson in 1969 by improving a little more the language BCPL which was created by
Martin Richards, so Ken Thompson named his language in honor of Martin Richards.
BCPL was created in 1966 by Martin Richards to combine the basic features of all other
programming languages of the time. Which was further improvised by Ken Thompson for his
use and created the B language.
The biggest drawback of B Language was that there was no concept of “Data Types”
(everything was expressed in machine language) and B Language did not provide the
functionality of “Structure”.
