Generic Root: of a number is sum of all the digits of the number until we get a single-digit output.

If user input number is 12345, then we add all the individual digits of the number i.e., 1 + 2 + 3 + 4 + 5 = 15. We got 15. Now we add individual digits of number 15 i.e., 1 + 5 = 6. So Generic Root of number 12345 is 6.

        while(num)
  {
            m = num%10;
            num = num/10;
            sum += m;
        }
        if(sum > 10)
            num = sum;
        else
            break;
    }

    printf("Generic Root is: %ld\n",sum);

return 0;
