From cppreference.com
< cpp‎ | iterator‎ | counted iterator

template <class I2> requires std::assignable_from<I&, const I2&> constexpr counted_iterator& operator=( const counted_iterator<I2>& other ); |  | (since C++20)

The underlying iterator and length are assigned with those of `other`.

### Parameters

other | - | iterator adaptor to assign from

### Return value

*this.

### Example

Run this code

    #include <algorithm>
    #include <cassert>
    #include <initializer_list>
    #include <iterator>

    int main()
    {
        auto a = {3, 1, 4, 1, 5, 9, 2};
        std::counted_iterator<std::initializer_list<int>::iterator> p(begin(a), size(a)-2);
        std::counted_iterator<std::initializer_list<int>::iterator> q;
        assert(q.count() == 0);
        assert(q.count() != p.count());
        q = p;
        assert(q.count() == p.count());
        assert(std::ranges::equal(p, std::default_sentinel, q, std::default_sentinel));
    }
