What keyword is used to declare an 'iterator' inside the container class before it is defined?

  1. class

  2. struct

  3. typename

  4. interface

The correct answer is: class

An iterator is an object that allows us to traverse through a container, such as a list or vector. In order to declare an iterator, the keyword 'class' is used in the container class before it is defined. This is necessary for declaring a member function that will use the iterator, and also for declaring an iterator type in the container class. The other options, such as 'struct', 'typename', and 'interface', are not applicable for declaring iterators.
