History of C Programming Language

The history of the C language is interesting to know. In this tutorial, we will understand the history & evolution of C Language.


The C programming language came out of Bell Laboratories of AT&T (American Telephone & Telegraph) in 1972. Dennis Ritchie is known as the founder of the C language. It was developed to overcome the problems of previous languages such as B, BCPL, etc. Initially, C language was developed along with the UNIX operating system, and is strongly linked with UNIX operating system. It inherits many features of previous languages such as B and BCPL. Let's see the programming languages that were developed before the C language.

List Of Programming Languages Developed before C Language:

Traditional CDennis Ritchie1972
K & R CKernighan & Dennis Ritchie1978
ANSI CANSI Committee1989
ISO CISO Committee1990
C99Standardization Committee1999
Standardization of C Language:

During initial days C Language was limited to the UNIX operating system, but as it started spreading around the world, it became commercial, and numerous compilers for other cross-platform systems were released. Now a days, C runs under a variety of operating systems and hardware platforms. As it started evolving many different versions of the language were released. Because the systems were still using earlier versions, it was occasionally challenging for the engineers to maintain the most recent version. The American National Standards Institute (ANSI) established a commercial standard for C language in 1989 to ensure that it would remain the industry standard. The International Standards Organization (ISO) later certified it in 1990. C programming language is also called as ANSI C.
