How to initialize a string set in C++?

https://stackoverflow.com/questions/12333783/how-to-initialize-a-string-set-in-c

Using C++11:

std::set<std::string> str = {"John", "Kelly", "Amanda", "Kim"};

Otherwise:

std::string tmp[] = {"John", "Kelly", "Amanda", "Kim"};
std::set<std::string> str(tmp, tmp + sizeof(tmp) / sizeof(tmp[0]));
