std::ranges...djacent_view(3) C++ Standard Libarystd::ranges...djacent_view(3)

NAME
       std::ranges::adjacent_view::adjacent_view      -	    std::ranges::adja-
       cent_view::adjacent_view

Synopsis
	  adjacent_view() requires  std::default_initializable<V>  =  default;
       (1) (since C++23)
	  constexpr	 explicit      adjacent_view(	   V	  base	    );
       (2) (since C++23)

	  Constructs an	adjacent_view.

	  1) Default constructor. Value-initializes the	underlying view.
	  2) Initializes the underlying	view base_ with	std::move(base).

Parameters
	  base - the underlying	view

Example
       // Run this code

	#include <iostream>
	#include <ranges>
	#include <string>
	#include <tuple>

	template<class... Ts>
	void print(std::tuple<Ts...> const& tuple)
	{
	    std::apply([&](auto&& arg, auto&&... args)
	    {
		std::cout << arg;
		((std::cout << args), ...);
	    }, tuple);
	    std::cout << '\n';
	}

	int main()
	{
	    const std::string v{"ABCDEF"};
	    constexpr int window_size{4};

	    std::cout << "v: " << v << '\n';

	    auto view =	std::views::adjacent<window_size>(v); // overload (2)

	    for	(auto const& tuple : view)
		print(tuple);
	}

Output:
	v: ABCDEF
	ABCD
	BCDE
	CDEF
