The element is constructed in-place by callingallocator_traits::constructwithargsforwarded. A similar member function exists,push_back, which eithercopies or movesan existing object into the container. 简而言之,push_back会构造一个临时对象,这个临时对象会被拷贝或者移入到容器中,然而emplace_back会直接根...

It's supposed to read each line, determine what kind of question it is and then store it into a container of "TriviaQuestions". I've most of it I think but when I'm trying to use push_back it gives me no instance of overloaded function "std::vector<_Ty, _Alloc>::push_back [wi...

However, I have found that while I can create vectors, I cannot use their functions. In particular, push_back() causes the application to abort and run to its exit() function. I read in another thread that this might be caused by having no heap memory available, so I made sure to ch...
