std::counted_iterator<I>::operator*,->

constexpr decltype(auto) operator*();
 (1) (since C++20) 
constexpr decltype(auto) operator*() const
    requires /*dereferenceable*/<const I>;
 (2) (since C++20) 
constexpr auto operator->() const noexcept
    requires std::contiguous_iterator<I>;
 (3) (since C++20)
1-2) Returns a reference to the current element. The behavior is undefined if this->count() <= 0. The function's body is equivalent to return *current;.
3) Returns a pointer to the current element. The function's body is equivalent to return std::to_address(current);.

Parameters

(none).

Return value

Reference or pointer to the current element.

Example

#include <complex>
#include <iostream>
#include <iterator>
using std::operator""i;
 
int main()
{
    const auto il = { 1.i, 2.i, 3.i, 4.i, 5.i };
 
    for (std::counted_iterator i{il.begin() + 1, 3}; i != std::default_sentinel; ++i)
        std::cout << *i << ' ';
    std::cout << '\n';
 
    for (std::counted_iterator i{il.begin() + 1, 3}; i != std::default_sentinel; ++i)
        std::cout << i->imag() << ' ';
    std::cout << '\n';
}

Output:

(0,2) (0,3) (0,4)
2 3 4
