Why to use 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 inside a program file.

History

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 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.
