Vectors are one of the single most useful and most used objects in the STL. They are easy to use, and remove the burden of memory management from the user. It is possible to partially control memory usage by using functions like reserve, but nothing is provided to free up excess memory. Users have come up with ways to trim a vector by hand, but with the advent of the new C++0x and its move semantics, the classic solution of copy-swaping has become excessively expensive. This article seeks to find a better solution.
