Iterators
Overview
Iterators are a generalization of pointers, which means that we can have access to a sequence elements without knowing the element type or the position. An iterator is an object that can iterate or navigate or traverse over elements in the containers that represent data structures. There are five iterator categories according to operations defined on them.Section Pages
Input Iterator
Input iterator reads forward and is provided by istream
Output Iterator
Output iterator steps forward with write access and is provided by ostream and inserter
Forward Iterator
Forward iterator may store and retrieve values
Bidirectional Iterator
Bidirectional iterator performs forward and backward moving
Random Access Iterator
Random access iterator allows you to access elements in any order
