C
Language Overview
The C
programming language 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 first 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 applications programs have been written in C. The 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 of B language, which was introduced around 1970.
- The language was formalized in 1988 by the American National Standard Institute. (ANSI).
- The UNIX OS was totally written in C by 1973.
- Today, C is the most widely used and popular System Programming Language.
- Most of the state-of-the-art softwares have been implemented using C.
- Today's most ][popular Linux OS and RBDMS MySQL have been written in C.
Why to
use C?
C was initially used for system development work, in
particular the programs that make up the operating system. C was adopted as a
system development language because it produces code that runs nearly as fast
as code written in assembly language. Some examples of the use of C might be:
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 extension ".c";
for example, hello.c. You can use "vi", "vim" or any other
text editor to write your C program into a file.
This tutorial assumes that you know how to edit a text file
and how to write source code using any programming language.
