Introduced in CPP98, CPP Iterators provide sequential access to elements in containers like vectors, lists, and maps. They enable traversing collections without exposing underlying implementation details, supporting a consistent traversal interface across various containers.
Standard CPP Iterators include forward_iterator, bidirectional_iterator, and random_access_iterator. These iterators are central to the Standard Template Library (STL) and support algorithms like sort, find, and copy.
