C PROGRAM AND CONTENTS
C is a general-purpose, procedural, imperative computer programming language developed in the early 1970s by Dennis Ritchie for use on the Unix operating system. It has since spread to many other operating systems, and is now one of the most widely used programming languages. C also has had a great influence on many other popular languages, especially C++ which was originally designed as an enhancement to C. It is the most commonly used programming language for writing system software, though it is also widely used for writing applications.
