What is an iterator class?, C/C++ Programming

Assignment Help:

A: A class which is used to traverse through the objects maintained through a container class. There are _ve categories of iterators: output iterators, input iterators, forward iterators, bidirectional iterators, random access. An iterator is an entity which gives access to the contents of a container object exclusive of violating encapsulation constraints. Access to the contents is granted onto a one-at- a-time basis in order. The order may be storage order (as in queues and lists) or some arbitrary order (as in array indices) or in according to some ordering relation (as in an ordered binary tree). The iterator is a construct that provides an interface that, while called, yields either the next element in container, or some value mentioning the fact that there are no more elements to verify. Iterators hide the details of access to and update of the elements of a container class. Something as a pointer.
