C is a general purpose high level language that was originally developed by Dennis M. Ritchie to devlop the unix operating system at BELL LABS .C was originally first implemented on the DEC PDP-11 computer in 1972.
In 1972, Brian kernighan and Dennis M. Ritchie produced the first publically available description of C ,now known as K&R standard
the unix operating system ,the C compiler and essentially all UNIX aplication program have been written in C .C has now become widely used proffesional language for various reasons .
Easy to learn.
It produces efficient programs
It can handle low level activities
It can be compiled on a variety of computer platforms
Facts about C-:
C was invented to write an operating system called UNIX.
C is a successor of B language which was introduced around the early 1970s.
The language was formalized in 1988 by the American National Standard Institute.
The unix OS was totally wriiten in C.

Today's most popular Linux OS and RDBMS My SQl have been written in C.
Why use C-:
C was initially used for system devlopment work ,particularly the programs that make up the operating system .C was adopted as a system devlopment language because it produces code that runs nearly as fast in assembly language .some examples of the use of C might be-
A C program can vary from 3 lines to millions of lines and it should be written into one or more text files with extension ".C" ;for wxample ,hello.c.you can use "vi","vim" or any other text editor to write your C program into a file.
