Palindrome Problem in C++

[wolle]

The problem is that the program returns false even when the number is a palindrome.

Are you sure? I could not spot a bug, so I ran your code with jverd's test set in #3 and the results are identical. It suggests your code is working. Still, it will not work with negative integers. If you want that you need to make this change to the while loop,

  while (tempOriginal != 0) {

And it will only work with integers up to 9-10 digits. That is the limit for a 32-bit integer. You can double this by using a 64-bit integer (a long long int).
