Introduction

C is a popular general-purpose programming language created by Dennis Ritchie at Bell Labs between the years 1969 and 1973. It was originally written for the DEC PDP-11 system that run the UNIX operating system.

C was influenced by the programming language B, developed by Ken Thompson - one of the principal creators of Unix - in 1970 at Bell Labs for non-numeric computations. B in turn is a remniscent of the earlier programming language called BCPL, a simple typeless language, designed by Martin Richards in 1966 at the University of Cambridge.

In 1978, Brian Kernighan along with Dennis Ritchie published the well-known tutorial on the language called The C Programming Language.
