1) Used to obtain the iterator type of the typeT.
2) Used to obtain the constant iterator type of the
range type
R.
3) Used to obtain the sentinel type of the range typeR.
4) Used to obtain the constant sentinel type of the range typeR.
[edit]Template parameters
iterator_t can be applied to non-range types, e.g. arrays with unknown bound.
[edit]Defect reports
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
