Types of iterator : Output vs. Input vs. Forward vs. Random Access Iterator

by

If you can, find and read “The C++ Standard Library: A Tutorial and Reference”. This book contains a whole chapter about STL iterators.

Here is a little something from the book:

Iterator Category  Ability                          Providers
-----------------  -------------------------------  ----------------------------
Input iterator     Reads forward                    istream
Output iterator    Writes forward                   ostream, inserter
Forward iterator   Reads/writes forward             forward_list,
                                                      unordered_[multi]set,
                                                      unordered_[multi]map
Bidirectional it.  Reads/writes forward/backward    list, [multi]set, [multi]map
Random access it.  Reads/writes with random access  vector, deque string, array
