Iterators are a generalization of pointers in C++ and have similar semantics. They allow a program to navigate through di erent types of containers in a uniform manner.

abstract: We propose a set of class templates that help programmers build standard-conforming iterators, both from scratch and by adapting other iterators. Iterators play an important role in …

The iterator objects themselves are required to support the following two methods, which together form the iterator protocol: iterator object itself. This is required to allow both containers and …

Iterators are objects that provide access to the elements in a collection.

Forward Iterator An input iterator that allows us to make multiple passes All STL container iterators fall here

The ITERATOR pattern gives a clean interface for element-by-element access to a collection, in-dependent of the collection’s shape. Imperative iterations using the pattern have two …

By including the method iter () in our fibnum class, we informed the Python interpreter that we wish to use this class as an iterator. We also had to include the method next(), which as its …
