== Incorrect type requirements for C++11 ==

For vector::resize C++11 standard states: "T shall be MoveInsertable and DefaultInsertable into *this." for overload (1) and "T shall be MoveInsertable into *this and CopyInsertable into *this." for overload (2). Same for deque::resize. For list and forward_list there is no MoveInsertable requirements - only DefaultInsertable is needed in first overload. Wiki structure seems to complex for me to correct this myself though.
:Many thanks! I've made the correction. --[[User:D41D8CD98F|D41D8CD98F]] ([[User talk:D41D8CD98F|talk]]) 05:38, 2 November 2014 (PST)

:: Hi! The error is still there. Descriptions for vector::resize and deque::resize from the standard: "T shall be MoveInsertable and '''DefaultInsertable''' into *this." '''for overload (1)''' and "T shall be '''MoveInsertable''' into *this and CopyInsertable into *this." '''for overload (2)'''.
:: Same for std::deque
::: Replaced DefaultConstructible with DefaultInsertable (you're right and this is the same for all four containers that share this template). There is no MoveInsertable requirement for overload 2 in C++14 or the current C++17 WP (it would be redundant anyway). Back in C++11, vector::resize was defined in terms of insert/erase and did not formally require CopyInsertable for overload 2 and only required CopyInsertable (not DefaultInsertable or MoveInsertable) for overload 1. DefaultInsertable didn't even exist in C++11. We could mention C++11 in a note, but I find it hard to do meaningfully. --[[User:Cubbi|Cubbi]] ([[User talk:Cubbi|talk]]) 07:35, 9 December 2014 (PST)
