Так как же всё-таки быстро конкатенировать строки в C++?

Всем практикующим программистам приходится конкатенировать строки. Именно конкатенировать, у нас не какой-то там JavaScript или PHP, у нас в C++ это называется вот таким заумным словом. Программисты на других языках без излишних мудрствований строки просто "складывают", даже не особо задумываясь об этой операции. Ведь что может быть проще, чем return "The answer is " + str_answer + ", count is " + count; Но если для скриптописателей простительно не думать о том, что стоит за такой простой записью, для опытного разработчика не приемлемо так безответственно подходить к такому важному вопросу. Опытный разработчик, представив такой код на C++, сразу видит ужасающую бездну проблем, которые может породить такой подход.

"cishet" should be "cis het" or "cis/het" because it's two words. People concatenate way too many things in English, especially in American English.

Also a million others: "someday", "hashtag", "cannot", et al.
