C Arithmetic Operations On Character

Arithmetic Operations On Character :

C Programming Allows you to Manipulate on String
Whenever the Character is variable is used in the expression then it is automatically Converted into Integer Value called ASCII value
All Characters can be Manipulated with that Integer Value.(Addition,Subtraction)

Examples :

Possible Ways of Manipulation :
Way 1: Displays ASCII value[ Note that %d in Printf ]

char x = 'a';
printf("%d",x); // Display Result = 97

Way 2 : Displays Character value[ Note that %c in Printf ]

char x = 'a';
printf("%c",x); // Display Result = a

Way 3 : Displays Next ASCII value[ Note that %d in Printf ]

char x = 'a' + 1 ;
printf("%d",x);
// Display Result = 98 ( ascii of 'b' )

Way 4 Displays Next Character value[Note that %c in Printf ]

char x = 'a' + 1;
printf("%c",x); // Display Result = 'b'

Way 5 : Displays Difference between 2 ASCII in Integer[Note %d in Printf ]

char x = 'z' - 'a';
printf("%d",x);
/* Display Result = 25 
    (difference between ASCII of z and a ) */

Way 6 : Displays Difference between 2 ASCII in Char [Note that %c in Printf ]

char x = 'z' - 'a';
printf("%c",x);
/* Display Result = ↓ 
      ( difference between ASCII of z and a ) */
