C Reverse Number 

For example, if the user enters 411 then the output will:

The reverse of 411 is 114

#include<stdio.h>
int main()
{
 int orig,save,r,rev=0;
  printf("\n Enter the number:");
  scanf("%d",&orig);.
   save=orig;
    while(orig!=0)
   {
    r=orig%10;
    rev=rev*10+r;
    orig=orig/10;
   }
   printf("The reverse of %d is %d",save,rev);
 return 0;
}
