推荐答案

实际上， std :: basic_string< char> 的typedef。 std :: basic_string 是专为字符串操作设计的容器类。此容器可用于宽字符（ wchar_t ）;对于这种情况，其typedef将 wstring 。

It's a typedef of std::basic_string<char>, actually. std::basic_string is a container class specifically designed for string operations. This container can be used for wide characters (wchar_t) as well; for that case its typedef would be wstring.
