C Program To Reverse The Digits

Here We will write a Program to reverse the digits of a given integer using looping. 

#include<stdio.h>
int main()
{
  int n, rev=0, rem;
   printf("Enter the no : ");
   scanf("%d",&n);
   while(n!=0)
   {
   rem=n%10;
    rev=rev*10+rem;
    n=n/10;
  }
printf("Reverse = %d",rev);
return 0;
}

INPUT :  137

OUTPUT : Reverse = 731
