如果字符串确实只是一个单词，则 std :: string大写= boost :: locale :: to_title（示例）应该这样做。否则，您所拥有的将非常紧凑。

If the string is indeed just a single word, std::string capitalized = boost::locale::to_title (example) should do it. Otherwise, what you've got is pretty compact.

编辑：只是注意到 boost :: python 命名空间有一个 str 类和一个 capitalize（）方法，听起来像它适用于多字串（假设您想要您描述的内容而不是标题的大小写）。但是，仅使用python字符串获得该功能可能不是一个好主意。

just noticed that the boost::python namespace has a str class with a capitalize() method which sounds like it would work for multi word strings (assuming you want what you described and not title case). Using a python string just to gain that functionality is probably a bad idea, however.
