std::ranges...ansform_view(3) C++ Standard Libary std::ranges...ansform_view(3) NAME std::ranges::adjacent_transform_view::adjacent_transform_view - std::ranges::adjacent_transform_view::adjacent_transform_view Synopsis adjacent_transform_view() = default; (1) (since C++23) constexpr explicit adjacent_transform_view( V base, F fun ); (2) (since C++23) Constructs an adjacent_transform_view. 1) Default constructor. Default-initializes the underlying data members fun_ and inner_. 2) Move constructs the underlying data members: fun_ with std::move(fun) and inner_ with std::move(base). Parameters base - the underlying view fun - the N-ary transformation function Example // Run this code #include <algorithm> #include <iostream> #include <iterator> #include <ranges> int main() { constexpr static auto v = {1, 2, 3, 4, 5}; constexpr auto mul = [](auto... x) { return (... * x); }; constexpr auto view = std::views::adjacent_transform<3>(v, mul); std::ranges::copy(view, std::ostream_iterator<int>(std::cout, " ")); std::cout << '\n'; } Output: 6 24 60 http://cppreference.com 2024.06.10 std::ranges...ansform_view(3)
