Program to find whether a given number is palindrome or not

We have to implement an algorithm to check the number is palindrone or not

	#include<stdio.h>
	int main(){
	int n,r,res=0,a;
	printf("ENter a number : ");
	scanf("%d",&n);
	a=n;
	while(n!=0){
	r=n%10;
	res=res*10+r;//321
	n=n/10;
	}
	printf("reverse is : %d\n",res);
	if(a==res){
	printf("palindrome");
	} else{
	printf("not a palindrome");
	}
	return 0;
	}
