您可以使用std::vector的成员函数将数据导出到其他容器中。例如,如果您想将数据导出到std::deque中,可以使用以下代码: 代码语言:cpp 复制 std::vector<int> vec = {1, 2, 3, 4, 5}; std::deque<int> deq(vec.begin(), vec.end()); 总之,您可以使用std::vector的成员函数将数据导出到其他数据结构或...

note: say ‘typename std::vector<T*,std::allocator<T*> >::iterator’ if a type is meant 解决方案是使用关键字"typename",如前所述: 123 typename std::vector<T*>::iterator it = v.begin(); for( ; it != v.end(); ++it) { ... 相关讨论 您应该详细说明,这仅在T是模板参数时适用...
