C is a general-purpose, high-level language that was originally developed by Dennis M. Ritchie to develop the UNIX operating system at Bell Labs. C was originally implemented on the DEC PDP-11 computer in 1972.

In 1978, Brian Kernighan and Dennis Ritchie produced the first publicly available description of C, now known as the K&R standard.

The UNIX operating system , the C compiler, and essentially all UNIX application programs have been written in C. C has now become a widely used professional language for various reasons.

Easy to learn
Structured language
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 to the B language, which was introduced around the early 1970s.
The language was formalized in 1988 by the American National Standard Institute (ANSI).
The UNIX OS was written in C.
Today, C is the most widely used and popular system programming language.
Most of the state-of-the-art software has been implemented using C.
Today’s most popular Linux OS and RDBMS MySQL have been written in C.

Why use C?

C was initially used for system development work, particularly the programs that make up the operating system . C was adopted as a system development language primarily because of its efficiency, as it produces code that runs almost as swiftly as assembly language code. Some examples of the use of C.

Operating Systems
Language Compilers
Assemblers
Text Editors
Print Spoolers
Network Drivers
Modern Programs
Databases
Language Interpreters
Utilities

C Programs

A C program can vary from 3 lines to millions of lines, and it should be written into one or more text files with the extension “.c”; for example, hello.c. You can use “Note Pad” or any other text editor to write your C program into a file.

Note:

This tutorial assumes that you know how to edit a text file and how to write source code inside a program file.
