<algorithm>

Standard Template Library: Algorithms

The header <algorithm>
A range is any sequence of objects that can be accessed through iterators or pointers, such as an array or an instance of some of the . Notice though, that algorithms operate through iterators directly on the values, not affecting in any way the structure of any possible container (it never affects the size or storage allocation of the container).
