C Tutorial : This tutorial is designed to be a stand-alone introduction to C, even if you’ve never programmed before.

C is a general-purpose high level language that was originally developed by Dennis Ritchie for the Unix operating system. It was first implemented on the Digital Eqquipment Corporation PDP-11 computer in 1972.

The Unix operating system and virtually all Unix applications are written in the C language. 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 computers.

Facts about C

  • C is a successor of B language which was introduced around 1970.
  • The language was formalized in 1988 by the American National Standard Institue (ANSI).
  • C was invented to write an operating system called UNIX.
  • Today C is the most widely used System Programming Language.
  • Most of the state of the art software have been implemented using 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 adoped 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
  • Text Editors
  • Assemblers
  • Network Drivers
  • ┬áModern Programs
  • Print Spoolers
  • Data Bases
  • Language Interpreters
  • Utilities

C Program File

All the C programs are writen into text files with extension “.c” for example hello.c. You can use “vi” 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 programming insturctions inside a program file.

C Compilers

When you write any program in C language then to run that program you need to compile that program using a C Compiler which converts your program into a language understandable by a computer. This is called machine language (ie. binary format). So before proceeding, make sure you have C Compiler available at your computer. It comes alongwith all flavors of Unix and Linux.

If you are working over Unix or Linux then you can type gcc -v or cc -v and check the result. You can ask your system administrator or you can take help from anyone to identify an available C Compiler at your computer.
