[edit]

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

Constructs achunk_view, initializing the underlying data members:

move constructs thebase_ withstd::move(base),
initializes the "chunk size"n_ withn.

In addition, ifV models exactly theinput_range, the constructor initializes the following exposition-only data members:

initializes theremainder_ with0,
default-initializes thecurrent_.

The behavior is undefined ifn is less than or equal to0.

[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,[](autoconst v){for(auto e: v)std::cout<< e<<' ';std::cout<<'\n';});}

Output:

0 1 2 34 5 6 78 9
