Constructs a new iterator adaptor.

1) Default constructor. The underlying iterator is value-initialized. Operations on the resulting iterator have defined behavior if and only if the corresponding operations on a value-initialized Iter also have defined behavior.
2) The underlying iterator is initialized with x (until C++20)std::move(x) (since C++20).
3) The underlying iterator is initialized with that of other. The behavior is undefined if U is not convertible to Iter (until C++20)This overload participates in overload resolution only if U is not the same type as Iter and std::convertible_to<const U&, Iter> is modeled (since C++20).

Parameters

x - iterator to adapt
other - iterator adaptor to copy

Example

Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR Applied to Behavior as published Correct behavior
