# std::ranges::adjacent_view<V,N>::iterator<Const>::operator*

From cppreference.com
< cpp‎ | ranges‎ | adjacent view‎ | iterator

constexpr auto operator*() const; |  | (since C++23)

Returns the elements into V the underlying array of iterators points to.

Let `current_` be an underlying array of iterators.

Equivalent to:

    return __tuple_transform([](auto& i) -> decltype(auto) { return *i; }, current_);

### Parameters

(none)

### Return value

The current element, which is a std::tuple of references to underlying elements.

### Notes

operator-> is not provided.

### Example

A link to test: Compiler Explorer/g++-13

Run this code

    #include <ranges>
    #include <tuple>

    int main()
    {
        constexpr static auto v = {0, 1, 2, 3, 4, 5};
        //                               └──┬──┘
        //                                  └─────────────────┐
        constexpr auto view {v | std::views::adjacent<3>}; // │
        constexpr auto iter {view.begin() + 2};            // │
        //              ┌────────────────────┬────────────────┘
        //              │                 ┌──┴──┐
        static_assert(*iter == std::tuple{2, 3, 4});
    }
