The page contains a major error. It states that no iterators or references are invalidated when the capacity is sufficient to accommodate the new element. This is incorrect. Any insertion operator on a vector always invalidates all iterators and references that refer to the point of insertion and past the point of insertion. For this reason `push_back` always invalidates the `end()` iterator. | The page contains a major error.

The page contains a major error. It states that no iterators or references are invalidated when the capacity is sufficient to accommodate the new element. This is incorrect. Any insertion operator on a vector always invalidates all iterators and references that refer to the point of insertion and past the point of insertion. For this reason `push_back` always invalidates the `end()` iterator. 173.11.122.193 10:45, 5 July 2013 (PDT)
