/* C++ program to check whether a number is palindrome or not */

#include <iostream>
using namespace std;

int main()
{
  int n, num, digit, rev = 0;
     cout << "Enter a positive number: ";
     cin >> num;
     n = num;
     do
     {
         digit = num%10;
         rev = (rev*10) + digit;
         num = num/10;
     }while (num!=0);
     cout << " The reverse of the number is: " << rev << endl;
     if (n==rev)
       cout << " The number is a palindrome";
     else
       cout << " The number is not a palindrome";

    retu 0;
}

Output

Enter a positive number: 12321
The reverse of the number is: 12321
The number is a palindrome

Enter a positive number: 12331
The reverse of the number is: 13321
The number is not a palindrome
