1.      Program to check if a given number is a palindrome.

1. #include <iostream.h>

2. #include <conio.h>

3. int main() {

4.     int n, reversed = 0, remainder, original;

5.     cout << "Enter an integer: ";

6.     cin >> n;

7.     original = n;

8.     while (n != 0) {

9.         remainder = n % 10;

10.         reversed = reversed * 10 + remainder;

11.                 n /= 10;

12.     }

13.     if (original == reversed)

14.                 cout << original << " is a palindrome.\n";

15.     else

16.                 cout << original << " is not a palindrome.\n";

17.     getch();

18.     return 0;

20. }
