std::ranges...k_view::size(3) C++ Standard Libarystd::ranges...k_view::size(3) NAME std::ranges::chunk_view::size - std::ranges::chunk_view::size Synopsis constexpr auto size() requires ranges::sized_range<V>; (1) (since C++23) constexpr auto size() const requires ranges::sized_range<const V>; (2) (since C++23) Returns the number of elements, which is the smallest integer value that is not less than the quotient of dividing the size of underlying view base_ by the underlying data member n_, that holds the number passed to the constructor (0 if default constructed). Equivalent to return __to_unsigned_like(__div_ceil(ranges::distance(base_), n_)); Parameters (none) Return value The number of elements. Example // Run this code #include <ranges> int main() { constexpr static auto v = {1, 2, 3, 4, 5}; constexpr auto w{ std::ranges::chunk_view(v, 2) }; static_assert(w.size() == (5 / 2 + (5 % 2 ? 1 : 0))); } See also ranges::size returns an integer equal to the size of a range (C++20) (customization point object) ranges::ssize returns a signed integer equal to the size of a range (C++20) (customization point object) http://cppreference.com 2024.06.10 std::ranges...k_view::size(3)
