c++ - index or position in std::set

Question

I have a std::set of std::string. I need the "index" or "position" of each string in the set, is this a meaningful concept in the context?

I guess find() will return an iterator to the string, so my question might be better phrased as : "How do I convert an iterator to a number?".

Answer 1

std::distance is what you need. You will want, I guess std::distance(set.begin(), find_result)
