 INTRODUCATION OF C

----------------------------------------------------------------------------------------------------------------------------- ----------------------

 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 invented to write an operating system called UNIX.

 The UNIX OS was totally written in C.

 WHY C ?

--------------------------------------------------------------------------------------------------------------------------------------------------

 Operating Systems

 Language Compilers

 Assemblers

 Text Editors

 Print Spoolers

 Network Drivers

 Modern Programs

 Databases

 Language Interpreters

 Utilities

o 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.

 C PROGRAM BASICALLY CONSISTS OF THE FOLLOWING PARTS −

--------------------------------------------------------------------------------------------------------------------------------------------------

 Preprocessor Commands

 Functions

 Variables

 Statements & Expressions

 Comments

 C Keyword:

--------------------------------------------------------------------------------------------------------------------------------------------------

auto else long switch

break enum register typedef

case extern return union

char float short unsigned

const for signed void

continue goto sizeof volatile

default if static while

do int struct _Packed
