[edit] Example

#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));
