    Set the width to 4 and the fill character to '0'. This can be easily done by #include <iomanip> with:
    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.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.
