Arithmetic Operations on Characters

In C, we can perform arithmetic operations on characters because each character is represented by its ASCII value.

For example, if you have a character 'A', its ASCII value is 65.

Here's a simple example:

                    #include <stdio.h>
                        int main() {
                            char char1 = 'A';
                            char char2 = 'B';
                            int result = char2 - char1; // Subtracting ASCII values
                            printf("Result: %d\n", result);
                            return 0;
                        }

Output:
Result: 1

In this example, subtracting the ASCII values of 'A' and 'B' will give you the result of 1.

You can perform addition, subtraction, multiplication, or division on characters based on their ASCII values.

Keep in mind that the result will be an integer.
