Search, insertion, and removal have average constant-time complexity. Internally, the elements are not sorted in any particular order, but organized into buckets. Which bucket an element is placed into depends entirely on the hash of its value.

No, there is no standard function to extract decimal digits from an integer. In C++11, there is a function to convert to a string: std::string string = std::to_string (value); If you can't use C++11, then you could use a string stream: std::ostringstream stream; stream << value; std::string string = stream.str (); or old-school C formatting:
