std::ranges..._view::begin(3) C++ Standard Libarystd::ranges..._view::begin(3) NAME std::ranges::stride_view::begin - std::ranges::stride_view::begin Synopsis constexpr auto begin() requires (!__simple_view<V>); (1) (since C++23) constexpr auto begin() const requires ranges::range<const V>; (2) (since C++23) Returns an iterator to the first element of the stride_view. 1) Equivalent to return iterator<false>(this, ranges::be- gin(base_));. 2) Equivalent to return iterator<true>(this, ranges::begin(base_));. Overload (1) does not participate in overload resolution if V is a simple view (that is, if V and const V are views with the same iterator and sentinel types). Parameters (none) Return value Iterator to the first element of the view. Example A link to test: Compiler Explorer. // Run this code #include <print> #include <ranges> int main() { constexpr auto v = {'A', 'B', 'C'}; const auto x = v | std::views::stride(2); const auto y = v | std::views::reverse | std::views::stride(2); const auto z = v | std::views::stride(2) | std::views::reverse; std::println("{} {} {}", *x.begin(), *y.begin(), *z.begin()); } Output: A C C See also end returns an iterator or a sentinel to the end (C++23) (public member function) http://cppreference.com 2024.06.10 std::ranges..._view::begin(3)
