A Brief History of C programming Language :
C programming language was originally developed by Dennis Ritchie between 1969 and 1973 at AT&T Bell Labs in USA.
B was the precursor language of C. B was created by Ken Thompson at Bell Labs and was an interpreted language used in early versions of the UNIX. Over the time, they improved B language and created its logical successor C which is a compiled programming language.
The development of C programming language was closely tied to the development of the Unix operating system. Unix kernel was one of the first operating system kernels to be implemented in C. The portability and architecture neutrality of UNIX was the main reason for the initial success of both C and UNIX.
In 1978, Dennis Ritchie and Brian Kernighan published the first edition of The C Programming Language.
The American National Standards Institute began work on standardizing the C language in 1983, and completed the standard in 1989. The standardization of C programming language started in 1983 by American National Standards Institute(ANSI) and got completed in 1989.
In 1990, the ANSI C standard was adopted by the International Organization for Standardization.
