[#](http://github.com/Eelis/draft/tree/9adde4bc1c62ec234483e63ea3b70a59724c745a/source/algorithms.tex#L14225)
*Effects*:
- [(1.1)](#1.1)
If T is an array type, equivalent to destroy(begin(*location), end(*location))[.](#1.1.sentence-1)
- [(1.2)](#1.2)
Otherwise, equivalent to location->~T()[.](#1.2.sentence-1)
