] | Taking the modulo in `d = n % 10` makes `d` equal to the last digit of `n` in base 10. `n = n / 10` removes the last digit from `n`.
Modulo is essentially taking the remainder, so let's say `n = 123`. Then `n / 10` is `12` and `n % 10` is `3`.
Removing the `n = n / 10` means that `n` doesn't change between each run... | Try these:
```
int n = 12;
printf("%d\n", n / 10);
int j = 12;
printf("%d\n", j % 10);
int x = 13;
x = x / 10; // right hand side of "=" get evaluated first
printf("%d\n", x);
```
Observe the output in each case.
Regarding your last point:
```
while (n > 0)
{
// some code.
}
```

] | Imagine you have a piece of paper with a hole in it just big enough to show one digit. To get the sum of the digits you have to put that paper over your number so the ones digit shows.
