C/C++ :: Program Takes Integer Input And Displays Each Digit On New Line From Right To Left

I'm trying to create a program that takes an integer input and displays each digit on a new line from right to left.

An example of this would be:

Enter an integer: 657
Digit (1): 7
Digit (2): 5
Digit (3): 6

So far I have this:

#include <stdio.h>
#include <math.h>
int main() {
int i, input, output;
printf("Enter an integer: ");
scanf("%d", &input);
if(input == 0)
printf("Digit (1): 0
");

[Code] ....

It works perfectly fine, but I just learned that I am not allowed to use the #include <math.h> so I have to take out floor, log, and pow.

I'm pretty sure I have to do some sort of while or for loop to get the results, but how to do it.
