std::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:
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.
[edit] Parameters
base
-
the adapted view
n
-
the chunk size
[edit] 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
