constexpr auto begin ( ) requires ( ! __simple_view < V > ) ;

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 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
