[duplicate] http://stackoverflow.com/questions/10127603/why-does-reallocating-a-vector-copy-instead-of-moving-the-elements by experimentally putting a foos.reserve 2 in front of the insertions this causes neither copy nor move to be executed. c c 11 stdvector..

How should I use FormatMessage() properly in C++? http://stackoverflow.com/questions/455434/how-should-i-use-formatmessage-properly-in-c flag. MSDN is a bit unclear on how insertions should be used but Raymond Chen notes that you should never.. a system message as you've no way of knowing which insertions the system expects. FWIW if you're using Visual C you can make..
What is wrong with `std::set`? http://stackoverflow.com/questions/5397616/what-is-wrong-with-stdset find_if call. Meanwhile the predicate 's set is empty the insertions within find_if are local . Therefore the loop afterwards will..
http://stackoverflow.com/questions/6602036/qvector-vs-qlist need a real linked list with guarantees of constant time insertions in the middle of the list and iterators to items rather than.. pointers to them. You gain all the benefits of quick insertions at both ends and reallocations involve shuffling pointers instead.. access individual elements quickly. The downside is that insertions are only efficient at one end. If you put something in the middle..
What does “constant” complexity really mean? Time? Count of copies/moves? [closed] http://stackoverflow.com/questions/8631531/what-does-constant-complexity-really-mean-time-count-of-copies-moves relative to the number of items in the list. That is O 1 insertions means that the number of items currently in the list does not.. in the list does not affect the overall complexity of insertions. The list could have 500 or 50000000 items in it and the complexity.. operation will be the same. For example std list has O 1 insertions and deletions the complexity of insertions is not affected by..
What is the difference between std::set and std::vector? http://stackoverflow.com/questions/8686725/what-is-the-difference-between-stdset-and-stdvector The same goes for removal. However if you do all of your insertions at once at initialization time then there's no problem. You..
