The iterator type of a possibly const-qualified zip_view, returned by zip_view::begin and in certain cases by zip_view::end. The type /*iterator*/ or /*iterator*/ treats the underlying views as const-qualified or non-const-qualified respectively.

1)zip_transform_view is a range adaptor that takes an invocable object and one or more view s, and produces a view whose ith element is the result of applying the invocable object to the ith elements of all views.

Notes ranges::range> is modeled if and only if for every type Vi in Views..., constVi models range. This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::ranges::zip_view::iterator is an associated class of the arguments.
