Recursive search through an integer

I was having some problem when trying to do a recursive in C programming. Here is the expected output:

Enter a number: 1234567
Enter the digit position: 3
rDigitValue1(): 5
rDigitvalue2(): 5 

And here is my code:

int rdigitValue1(int num, int k)
{
    int count = 0, output;
    if (count != k) {
        rdigitValue1(num / 10, k);
        count++;
    }
    else {
        output = (num % 10);
    }
    return output;
}

The parameter num is the number whereas the parameter k is the position. With these code, when I try to run the program, it just crashed without prompting any error message. Any idea?
