#include <stdio.h>

int main (void)

{

               int number;
               int reverse_number;
               int temp;

               //Input number.
               printf ("Input number: ");
               scanf ("%d", &number);

               //Finding the reverse number.

               temp = number;
               reverse_number = 0;
               while (temp != 0)
               {
                              reverse_number = reverse_number * 10 + temp % 10;
                              temp = temp / 10;
               }

               //Output the result.
               printf ("Reverse number: %d", reverse_number);

Output

Input number: 1234
Reverse number: 4321
