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 : ASCII value of : ‘a’ is 97 ASCII value of(…)
