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:
remainder_
with 0
, current_
. The behavior is undefined if n
is less than or equal to 0
.
base | - | the adapted view |
n | - | the chunk size |

#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'; }); }
