Why? I don''t know. You seem to have a very strange compiler. The code containsquite a lot of errors that would prevent it from being accepted by any C++compiler I know. The code contains quite a lot of errors(...) I use Microsoft Visual C++ and I see only two error: a.obj : error LNK2001: unresolved external symbol "classstd::basic_ostream<char,struct std::char_traits<char> > & __cdecloperator<<(class std::basic_ostream<char,struct std::char_traits<char>,class matrix2x2)" (??6@YAAAV?basic_ostream@DU? 这篇关于类矩阵的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
