標準C++附加的標頭檔案(3個)非必須

<hash_map><hash_set><slist>

TheStandard C++ library consists of 51 required headers.Thisimplementation also includes three additionalheaders,<hash_map>,<hash_set>,and <slist>,notrequired by the C++ Standard, for a total of 54 headers.Of these 54headers,16 constitute the Standard Template Library, or STL.These areindicated below with the notation
