C PROGRAMMING LANGUAGE

INTRODUCTION :
     
C is a general-purpose, imperative, procedural high level  language that was developed in 1972 by Dennis Ritchie at the Bell Telephone Laboratories. For the UNIX operating  system.  This C language is first implemented on the Digital Eqquipment  Corporation  computer in 1972, and now one of the most widely used programming languages. C has also influence many popular languages, especially C++, which was originally designed as enhancement to C . It is also most commonly used programming  languages. It is widely used for writing applications.

C CHARACTER SET

Types of Character Set 
    
       *  Letters
       *  Digits
       * Special characters

   Letters:
 . A to Z in capital and small letters
. In c language small latter and caps latter are distinct.
 
   Digits:
. Sequence of number is associated the letter 0 to 9.
 
   Special characters:

Symbol	Meaning
~	Tilde
!	Exclamation mark
#	Number sign
$	Dollar sign
%	Percent sign
^	Caret
&	Ampersand
*	Asterisk
(	Left parenthesis
)	Right parenthesis
_	Underscore
+	Plus sign
|	Vertical bar
\	Backslash
`	Apostrophe
–	Minus sign
=	Equal to sign
{	Left brace
}	Right brace
[	Left bracket
]	Right bracket
:	Colon
”	Quotation mark
;	Semicolon
<	Opening angle bracket
>	Closing angle bracket
?	Question mark
,	Comma
.	Period
/	Slash

    Simple C programn- Hello World

     INPUT:

1. #include <stdio.h>
2. int main()
3. {
4. // printf() displays the string inside quotation
5. printf("Hello, World!");
6. return 0;
7. }

    OUTPUT:

Hello, World!

Arithmetic Operator
 There are only five arithmetic operators in C language.

An arithmetic operator performs mathematical operations such as addition, subtraction, multiplication, division etc on numerical values (constants and variables).

Operator	Meaning of Operator
+	addition or unary plus
-	subtraction or unary minus
*	multiplication
/	division
%	remainder after division (modulo division) nihalvaidya29@gmail.com Example 1: Arithmetic Operators INPUT: #include <stdio.h> int main() { int a = 9,b = 4, c; c = a+b; printf("a+b = %d \n",c); c = a-b; printf("a-b = %d \n",c); c = a*b; printf("a*b = %d \n",c); c = a/b; printf("a/b = %d \n",c); c = a%b; printf("Remainder when a divided by b = %d \n",c); return 0; } OUTPUTS a*b = 36 a/b = 2 Remainder when a divided by b=1 C – while loop Syntax of while loop: while (condition test) { //Statements to be executed repeatedly // Increment (++) or Decrement (--) Operation } Flow Diagram of while loop Example of while loop #include <stdio.h> int main() { int count=1; while (count <= 4) { printf("%d ", count); count++; } return 0; } step1: The variable count is initialized with value 1 and then it has been tested for the condition. step2: If the condition returns true then the statements inside the body of while loop are executed else control comes out of the loop. step3: The value of count is incremented using ++ operator then it has been tested again for the loop condition.OUT#include <stdio.h> Example:#include <stdio.h> int main() { int var = 6; while (var >=5) { printf("%d", var); var++; } return 0; } Infinite loop: var will always have value >=5 so the loop would never end.
