C++ Program to check a number is Palindrome or not

Statement:Check a number is Palindrome or not.
Code:

//I) to check a number is Palindrome or not.

#include<iostream>

using namespace std;

void main()

{

       cout << "\t\t\tPlindrome Number\n\n";

       int num, rev, tmp, tmp2, i, j, rev1;

       rev = 0; i = 0; j = 1; rev1 = 0;

       cout << "Enter A Nmuber : ";

       cin >> num;

       tmp = num;

       while (tmp != 0) //to calculate reverse

       {

              tmp2 = tmp % 10; //number remainder 10 will assign to tmp2

              rev = rev * 10 + tmp2; //reverse of number is equal to rev*10+number%10

              tmp = tmp / 10; //updating the value of number

       }

       if (rev == num) //if reverse is equal to number

       {

              cout <<endl<< num << " Is Pandlirome.";

       }

       else //if reverse is not equal to number

       {

              cout <<endl<< num << " Is Not Palindrome.";

       }

       cout << "\n\n";

       system("pause");
