[edit] 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 ));
