    What is an Iterator class?

    A class that is used to traverse through the objects maintained by a container class. There are five categories of iterators:
    random access.
    input iterators
    forward iterators
    output iterators,
    bidirectional iterators.
    An iterator is an entity that gives access to the contents of a container object without violating encapsulation constraints.

    Define an Iterator class. An iterator class is used to iterate through objects of the container class.

    Re: What is an Iterator class?

    This is a base class template that can be used to derive iterator classes from it. It is not an iterator class and does not provide any of the functionality an iterator.

    Re: What is an Iterator class?

    This is a base class design that can be used to obtain iterator sessions from it. It is not an iterator category and does not offer any of the performance an iterator.

    Re: What is an Iterator class?

    Iterator is an interface. It is not a class. It is used to iterate through each and every element in a list.

    Re: What is an Iterator class?

    In the context of computer programming, Iteration is a process wherein a set of instructions or structures are repeated in a sequence a specified number of times or until a condition is met.
    When the first set of instructions is executed again, it is called an iteration. When a sequence of instructions is executed in a repeated manner, it is called a loop.
    Iteration is the repetition of a process in a computer program, usually done with the help of loops.

    Iterator is used to get objects one by one from any collection object.It allows you to traverse through the elements, add or remove elements.
