2. An iterator move constructed from the underlying iterator.

[edit] Example

#include #include #include #include   int main() { const auto v = { 0, 1, 2, 3, 4 }; auto x2 = [](int x) { return x << 1; }; std::ranges::transform_view tv{ v, x2 }; std::ostream_iterator ostr{ std::cout, " " };   std::ranges::copy(v, ostr), std::cout << '\n'; std::ranges::copy(tv.base(), ostr), std::cout << '\n'; std::ranges::copy(tv, ostr), std::cout << '\n'; }

Output:

0 1 2 3 4 0 1 2 3 4 0 2 4 6 8
