    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*

    Store the representation in a string, then reverse that string. Alternatively, access in reverse a std::bitset of that number.

    You mean change 12345 to 54321?
    That's not difficult. You should use '%' operator.
