Arithmetic Operations On Character in C Programming

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 :

1. ASCII value of : 'a' is 97
2. ASCII value of : 'z' is 121

---

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 ) */
