std::ranges::chunk_view::chunk_view(3) | C++ Standard Libary | std::ranges::chunk_view::chunk_view(3) |
NAME¶
std::ranges::chunk_view::chunk_view - std::ranges::chunk_view::chunk_view
Synopsis¶
constexpr explicit chunk_view( V base,
ranges::range_difference_t<V> (since C++23)
n );
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
