Question

the code snippet below takes an an integer (i.e. number) from the user and prints the count of all the digits in that number, however, if I enter a number contains 0 somewhere, it gets out of the while loop immediately (because of the while loop condition). I tried fixing this bug but I could not. Could you please help me out fixing it. Thank you.

int count = 0;
int rem = number % 10;

while(rem != 0) {
   number /= 10;
   ++count;
   rem = number % 10;

}//end while

printf("The count is %d", count);

No code need to be shared, if you can walk me through it by text, that would appreciated.

Thank you.

Answer 1

Perhaps it should be:

while (number != 0)

You don’t seem to need the other stuff (rem et al) unless you plan on doing more than just counting digits. And at any rate, you probably want rem = number % 10; before the division.
