std::ranges...djacent_view(3) C++ Standard Libary std::ranges...djacent_view(3) NAME std::ranges::adjacent_view::adjacent_view - std::ranges::adjacent_view::ad- jacent_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 http://cppreference.com 2024.06.10 std::ranges...djacent_view(3)
