How do I Print numbers in reverse using loop in c?

Hi!
I was asked to create a program that will get numbers from the user.
The numbers should always be positive and disregards the negative sign.
The numbers will then be converted to digits.
I need to print it in the right order as it looked like the number entered by the user.
I should also get the sum of the digits and tell if it is divisible by 3.
If the input of the user is 0 the program should end.

So here's my code:

#include <stdio.h>
#include <stdlib.h>
int main () {
	int input, individual, reverse=0; // declarations
	
do {	// loop infinitley except when input is 0
    printf ("Please Enter a number: "); // Statement to enter a number
	scanf ("%d", &amp;input); // scan input
    
	if (input!=0) { // to check if input is 0 or not if yes end program
	 int sum=0, i=1; // initial value of sum and i as counter
	 
     printf ("The Digits are "); // print the introductory text
    
     	while (input!=0) { // check if input is 0 or not
     	input = abs (input); // numbers should be positive so i use absolute
		individual= input%10; //gets modulo of input  
		sum += individual; // adds the digits
		input/=10; ++i; // divides digits and update counter
 		printf ("%d ", individual); // prints individual digit BUT SHOULD BE IN PROPER ORDER
        }
       
		printf ("\nThe Sum of the Digit(s) is %d\n", sum);// prints the sum
		
		if (sum % 3 == 0) { // checks if sum is divisible by 3
         printf ("This Number is divisible by 3!\n"); // prints
         }
         printf ("\n"); // break line
    }
    	
	else if (input == 0) { // ends the program if input is 0
      return 0;
      system ("pause");
    }
         
} while (1);        // infinite loop
        	
 	system ("pause");
}

Sample run:
Please Enter a number : 123
The Digits are 3 2 1
The sum of the digits is 6
this number is divisible by 3!

Please Enter a Number

What I wanted it to output is :
Please Enter a number : 123
The Digits are 123
The sum of the digits is 6
this number is divisible by 3!

Please Enter a Number
