std::ranges..._view::begin(3)  C++ Standard Libary std::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::begin(base_));.
	2) Equivalent to return iterator<true>(this, ranges::begin(base_));.

	Overload  (1) does not participate in overload resolution if V is a sim-
     ple 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
