drukowanie zawartości wektora 2d
to jest kod, który używam:
<code>std::vector<std::vector<double>> test; test.push_back(std::vector<double>(30)); std::vector<std::vector<double> >::iterator it=test.begin(), end=test.end(); while (it!=end) { std::vector<double>::iterator it1=it->first.begin(),end1=it->first.end(); while (it1!=end1) { std::copy(it1.begin(),it1.end(),std::ostream_iterator<double>(std::cout, " ")); ++it1; } ++it; } </code>
to jest błąd kompilacji, który otrzymuję:
<code>data.cpp:33:45: error: ‘class std::vector<double>’ has no member named ‘first’ data.cpp:33:68: error: ‘class std::vector<double>’ has no member named ‘first’ data.cpp:35:16: error: ‘class std::vector<double>::iterator’ has no member named ‘begin’ data.cpp:35:28: error: ‘class std::vector<double>::iterator’ has no member named ‘end’ data.cpp:35:34: error: ‘ostream_iterator’ is not a member of ‘std’ data.cpp:35:56: error: expected primary-expression before ‘double' </code>
wszelkie sugestie, jak to naprawić, abym mógł wydrukować zawartość testu
