<iterator> library in C++ STL

Iterators in C++ STL | Introduction

Functions

Iterator operations :

• std :: advance : Advance iterator
• std :: distance : Return distance between iterators
• std :: begin : Iterator to beginning
• std :: end : Iterator to end
• std :: prev : Get iterator to previous element
• std :: next : Get iterator to next element
• std :: next vs std :: advance
• All functions in Iterators in C++ STL

Iterator generators :

• std :: back_inserter : Construct back insert iterator
• std :: front_inserter : Constructs front insert iterator
• std :: inserter : Construct insert iterator
• std :: make_move_iterator : Construct move iterator

Types of Iterator Classes

• input_iterator : Input iterator category
• output_iterator : Output iterator category
• forward_iterator : Forward iterator category
• bidirectional_iterator : Bidirectional iterator category
• random_access_iterator : Random-access iterator category

Predefined iterators

• std :: reverse_iterator : Reverse iterator (class template )
• std :: move_iterator : Move iterator (class template )
• std :: back_insert_iterator : Back insert iterator (class template )
• std :: front_insert_iterator : Front insert iterator (class template )
• std :: insert_iterator : Insert iterator (class template )
• std :: istream_iterator : Istream iterator (class template )
• std :: ostream_iterator: Ostream iterator (class template )
• std :: istreambuf_iterator : Input stream buffer iterator (class template )
• std :: ostreambuf_iterator : Output stream buffer iterator (class template )
