Defined in header <ranges>
template <class T> using iterator_t = decltype(ranges::begin(declval<T&>()));	(1)	(since C++20)
template <class T> using sentinel_t = decltype(ranges::end(declval<T&>()));	(2)	(since C++20)

1) Used to obtain the iterator type of the type T.

2) Used to obtain the sentinel type of the type T.
