#include <stdio.h>
 
 main()
{
 
int num;    //number inputted by user
int n;     //temporary storage
int rev=0; //stores the reverse of that number
int digit; //stores the individual digits 
 
printf(" Enter the number to check if it's Palindrome or not: ");
scanf("%d", &num);
 
n=num;
 
do
{
digit=n%10;
rev=(rev*10)+digit;
n=n/10;
}
while(n>0);
 
if(rev==num)
{
printf("\n The number is a palindrome. ");
}
else
{
printf("\n The number is not a palindrome. ");
}
 
}


OUTPUT:

 Enter the number to check if it's Palindrome or not: 121
