Answer 1

I don't know what you want to do but if you want to add each element of any number then do like this :-

while(x > 0)
{
rem=x%10;
sum+=rem;
x/=10;
}

return sum;

Answer 2

Could you please explain the code.
What should the code do?

Answer 3

Avinesh

It should print the sum of each single digits,
If and only if sum is a single digit number.

Ex : n=5347, sum= 5+3+4+7 = 19 ( having two digits, thus again take sum of current sum(19).

Sum=1+9 = 10,
Again take sum.

Sum = 1+0 = 1 ( since sum is a single digit number, print sum = 1).
