    Set the width to 4 and the fill character to '0'. This can be easily done by #include <iomanip> with:
    Code:
    std::cout << std::setw(4) << std::setfill('0') << num << std::endl;
    By the way, we don't normally consider 12 to be a digit, unless you are expressing the number in base 13 or more.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
