zip_view takes any number of views and
produces a view of tuples of references
to the corresponding elements of the constituent views[.](#1.sentence-1)

The name views​::​zip denotes
a customization point object ([[customization.point.object]](customization.point.object "16.3.3.3.5 Customization Point Object types"))[.](#2.sentence-1)

Given a pack of subexpressions Es...,
the expression views​::​zip(Es...) is expression-equivalent to

- [(2.1)](#2.1)

auto(views​::​empty<tuple<>>) if Es is an empty pack,

- [(2.2)](#2.2)

otherwise, zip_view<views​::​all_t<decltype((Es))>...>(Es...)[.](#2.sentence-2)

[*Example [1](#example-1)*: vector v = {1, 2};
list l = {'a', 'b', 'c'};

auto z = views::zip(v, l);
range_reference_t<decltype(z)> f = z.front(); // f is a tuple<int&, char&>// that refers to the first element of v and lfor (auto&& [x, y] : z) { cout << '(' << x << ", " << y << ") "; // prints (1, a) (2, b)} — *end example*]
