                     A BRIEF GUIDE ON C PROGRAMMING 
LANGUAGE
Introduction to C
C is probably the most widely known 
programming language. 
It is used as the reference language for 
computer science courses all over the world, and 
it's probably the language that people learn the 
most in school along with Python and Java.

About C Programming
Procedural Language - Instructions in a C 
program are executed step by step.
Portable - You can move C programs from one 
platform to another and run it without any or 
minimal changes.

About C Programming 
cont.
Speed - C programming is faster than most 
programming languages like Java, Python, etc.
General Purpose - C programming can be used 
to develop operating systems, embedded 
systems, databases, and so on.

Why Learn C 
Programming?
C helps you to understand the internal 
architecture of a computer, how computer 
stores and retrieves information.
After learning C, it will be much easier to learn 
other programming languages like Java, Python, 
etc.

History of C language
C language has evolved from three different 
structured language ALGOL, BCPL and B 
Language.
In 1988, the language was formalised by 
American National Standard Institute(ANSI). 
In 1990, a version of C language was approved 
by the International Standard Organisation(ISO) 
and that version of C is also referred to as C89.

Facts about C
C was invented to write an operating system 
called UNIX.
C is a successor of B language which was 
introduced around the early 1970s.
The language was formalized in 1988 by the 
American National Standard Institute (ANSI).

Facts about C cont.
The UNIX OS was totally written in C.
Today C is the most widely used and popular 
System Programming Language.
Most of the state-of-the-art software have been 
implemented using C.
Today's most popular Linux OS and RDBMS 
MySQL have been written in C.

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.

Local Environment Setup
If you want to set up your environment for C 
programming language, you need the following 
two software tools available on your computer, 
(a) Text Editor and (b) The C Compiler.

The C Compiler
The source code written in source file is the 
human readable source for your program. 
It needs to be "compiled", into machine 
language so that your CPU can execute the 
program as per the instructions given.
