Recursion problem

Hey guys I have a question about this function (needs to calculate the number of digits of any integer). My problem is- How do I return 1 in case of the number that is given is 0 since 0 is a 1 digit number?

Code:

---

int numberOfDigits(int num);

int main()
{
        int number=1068;
        printf ("%d\n",numberOfDigits(number));
        return 0;
}

int numberOfDigits(int num)
{
        if (num==0)
        {
                return 0;
        }
        return 1 + numberOfDigits(num/10);
}

---

Thanks.

start your recursion one step futher

Code:

---

int numberOfDigits(int num)
{
        if (num> -10 && num <10)
        {
                return 1;
        }
        return 1 + numberOfDigits(num/10);
}

That totally works, thanks for the quick reply.
