c++ Programming Glossary: push_frontWhy does a push_back on an std::list change a reverse iterator initialized with rbegin? http://stackoverflow.com/questions/10085570/why-does-a-push-back-on-an-stdlist-change-a-reverse-iterator-initialized-with over a list from begin to end and then add elements using push_front. E.g. in the following code I initialize a list with elements.. with elements a b and c then loop over it and perform a push_front of the elements. The result should be cbaabc which is exactly.. itList testList.begin itList testList.end itList testList.push_front itList for std list std string const_iterator itList testList.begin..
Why does std::stack use std::deque by default? http://stackoverflow.com/questions/102459/why-does-stdstack-use-stddeque-by-default give a buffer of elements before front so that push_front is an efficient operation Aren't these elements wasted since..
C++ deque's iterator invalidated after push_front() http://stackoverflow.com/questions/1658956/c-deques-iterator-invalidated-after-push-front deque's iterator invalidated after push_front Just now I'm reading Josuttis' STL book. As far as I know c.. know it is array of large blocks c array of c arrays . So push_front inserts element at the beginning and if there is no space deque.. I really misunderstand the phrase ...after push_back and push_front all references stays valid but iterators don't same phrase can..

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 and a few pointers in the linked list are shuffled. Each push_front involves one allocation always of the same amount of memory.. less predictable in terms of runtime than a single list push_front but it's still referred to as constant amortized . On average..
