NAME

       std::default_sentinel_t

SYNOPSIS

       #include <iterator>

Detailed Description

       A sentinel type that can be used to check for the end of a range.

       For some iterator types the past-the-end sentinel value is independent of the underlying sequence, and a
       default sentinel can be used with them. For example, a std::counted_iterator keeps a count of how many
       elements remain, and so checking for the past-the-end value only requires checking if that count has
       reached zero. A past-the-end std::istream_iterator is equal to the default-constructed value, which can
       be easily checked.

       Comparing iterators of these types to std::default_sentinel is a convenient way to check if the end has
       been reached.
