constexpr decltype( auto ) operator[ ] ( difference_type n ) const requires ranges::random_access_range <Base>		(since C++23)

Returns an element at specified relative location.

Equivalent to: return *(*this + n);

Parameters

n

-

position relative to current location

Return value

The element at displacement n relative to the current location.

Example

Run this code

#include <ranges>
 
int main()
{
    constexpr static auto v = {'a', 'b', 'c', 'd', 'e'};
    constexpr auto view{v | std::views::stride(2)};
    constexpr auto iter{view.begin() + 1};
    static_assert(*iter == 'c');
    static_assert(iter[0] == 'c');
    static_assert(iter[1] == 'e');
}
