# std::ranges::chunk_view<V>::chunk_view

From cppreference.com
< cpp‎ | ranges‎ | chunk view

constexpr explicit chunk_view( V base, ranges::range_difference_t <V> n ); |  | (since C++23)

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

base | - | the adapted view
n | - | the chunk size

### Example

Run this code

    #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';
        });
    }

Output:

    0 1 2 3
    4 5 6 7
    8 9
