開發平台(Platform): (Ex: VC++, GCC, Linux, ...) linux 額外使用到的函數庫(Library Used): (Ex: OpenGL, ...) no 問題(Question)：如果在一個自訂的class叫Test裡有一個data member為ofstream record 請問要怎麼在這個class的constructor初始化？錯誤結果(Wrong Output)：程式碼(Code)：(請善用置底文網頁, 記得排版) public： Test(): record(new ofstream("record")) {} 補充說明(Supplement)：上述的code會出現以下error：對「std::basic_ofstream<char>::basic_ofstream(std::ofstream*)」的呼叫沒有匹配的函式 ../../include/god.h:18:110: 附註： candidates are: /usr/include/c++/4.6/fstream:629:7: 附註： std::basic_ofstream<_CharT, _Traits>::basic_ofstream(const char*, std::ios_base::openmode) [with _CharT = char, _Traits = std::char_traits<char>, std::ios_base::openmode = std::_Ios_Openmode] /usr/include/c++/4.6/fstream:629:7: 附註： no known conversion for argument 1 from 「std::ofstream* {aka std::basic_ofstream<char>*}」 to 「const char*」 /usr/include/c++/4.6/fstream:614:7: 附註： std::basic_ofstream<_CharT, _Traits>::basic_ofstream() [with _CharT = char, _Traits = std::char_traits<char>] /usr/include/c++/4.6/fstream:614:7: 附註： candidate expects 0 arguments, 1 provided /usr/include/c++/4.6/fstream:588:11: 附註： std::basic_ofstream<char>::basic_ofstream(const std::basic_ofstream<char>&) /usr/include/c++/4.6/fstream:588:11: 附註： no known conversion for argument 1 from 「std::ofstream* {aka std::basic_ofstream<char>*}」 to 「 const std::basic_ofstream<char>&」請問一下各位高手該怎麼宣告才不會錯呢＠＠ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.25.108
