3. Don't know witch one you want.
Code:
```#include <stdio.h>

//Get all the right digits
//returns id if id < 10
int getRightDigit(int id) {
int div = 10;
while (( id / div )  > 10 )
div *= 10;
return id % div;
}

//Get all the right digits
//returns 0 if id < 10
int getRightDigit1(int id) {
if ( id < 10 ) return 0;
int div = 10;
while (( id / div )  > 10 )
div *= 10;
return id % div;
}

int main(void) {
printf( "%d \n" , getRightDigit(332) );
printf( "%d \n" , getRightDigit1(2) );
return 0;
}```
