std::ranges...:stride_view(3) C++ Standard Libarystd::ranges...:stride_view(3) NAME std::ranges::stride_view::stride_view - std::ranges::stride_view::stride_view Synopsis constexpr explicit stride_view( V base, ranges::range_differ- ence_t<V> (since C++23) stride ); Constructs a stride_view initializing the underlying data members: * move construct the underlying view base_ with std::move(base), * construct the stride_ with stride. If stride < 1 the behavior is undefined. Parameters base - the source view stride - the stride value Example // Run this code #include <algorithm> #include <iostream> #include <iterator> #include <ranges> #include <string_view> void print(std::string_view rem, auto v, std::string_view term = "\n") { std::cout << rem << ": "; std::ranges::copy(v, std::ostream_iterator<int>(std::cout, " ")); std::cout << term; }; int main() { auto source = std::views::iota(1, 10); print("source", source); for (int stride_value : std::views::iota(1, 6)) { auto strided_view = std::views::stride(source, stride_value); print("stride", std::views::single(stride_value), "-> "); print("result", strided_view); } } Output: source: 1 2 3 4 5 6 7 8 9 stride: 1 -> result: 1 2 3 4 5 6 7 8 9 stride: 2 -> result: 1 3 5 7 9 stride: 3 -> result: 1 4 7 stride: 4 -> result: 1 5 9 stride: 5 -> result: 1 6 http://cppreference.com 2024.06.10 std::ranges...:stride_view(3)
