std::ranges::slide_view<V>:: end

From cppreference.com
Ranges library
Range adaptors
constexpr auto end ( )
requires ( ! ( /*simple-view*/ < V > && /*slide-caches-nothing*/ < const V > ) ) ;
(1) (since C++23)
constexpr auto end ( ) const
requires /*slide-caches-nothing*/ < const V > ;
(2) (since C++23)

Returns a sentinel or an iterator representing the end of the slide_view .

1) Let base_ and n_ be the underlying data members. Equivalent to:
If V models slide-caches-last , this function caches the result within the cached_end_ for use on subsequent calls. This is necessary to provide the amortized constant-time complexity required by the range .
2) Equivalent to begin ( ) + ranges:: range_difference_t < const V > ( size ( ) ) .

Parameters

(none)

Return value

A sentinel or an iterator representing the end of the slide_view .

Example

#include <iostream>
#include <ranges>
 
int main()
{
    static constexpr auto source = {'A', 'B', 'C', 'D'};
 
    for (const auto subrange: source | std::views::slide(3))
    {
        std::cout << "[ ";
        for (auto it = subrange.begin(); it != subrange.end(); ++it)
            std::cout << *it << ' ';
        std::cout << "]\n";
    }
}

Output:

[ A B C ]
[ B C D ]
