Constructs a chunk_view, initializing the underlying data members:

• move constructs the base_ with std::move(base),
• initializes the "chunk size" n_ with n.

In addition, if V models exactly the input_range, the constructor initializes the following exposition-only data members:

• initializes the remainder_ with 0,
• default-initializes the current_.

The behavior is undefined if n is less than or equal to 0.

Parameters

Example

#include <algorithm>
#include <iostream>
#include <ranges>

int main()
{
    auto i = std::views::iota(0, 10);
    auto w = std::ranges::chunk_view(i, 4);

    std::ranges::for_each(w, [](auto const v)
    {
        for (auto e : v)
            std::cout << e << ' ';
        std::cout << '\n';
    });
}
