== Description

Move the elements of (template parameter) `TARGET_TYPE` in the array starting at the specified `fromBegin` address and ending immediately before the specified `fromEnd` address into an uninitialized array of `TARGET_TYPE` at the specified `toBegin` address, moving into the specified `position` (after translating from `fromBegin` to `toBegin`) the specified `numElements` of the `TARGET_TYPE` from the array starting at the specified `first` address and ending immediately before the specified `last` address. Keep the pointer at the specified `fromEndPtr` address pointing to the first uninitialized element in `[fromBegin, fromEnd)]`, and the pointer at the specified `lastPtr` address pointing to the end of the moved range as the elements from the range `[ first, last)]` are moved from source to destination. The behavior is undefined unless `fromBegin <= position <= fromEnd`, the destination array contains at least `(fromEnd ‐ fromBegin) + numElements` uninitialized elements after `toBegin`, and `numElements` is the distance from `first` to `last`. If a copy constructor or assignment operator for `TARGET_TYPE` throws an exception, then any elements in `[ *lastPtr, last )]` as well as in `[ toBegin, ... )]` are destroyed, and the elements in the ranges `[ first, *lastPtr )]` and `[ fromBegin, *fromEndPtr )]` will have unspecified but valid values.

== Parameters
