std::ranges::stride_view<V>:: stride_view

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

Example

#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);
    }
}
