Adaptors

There are adaptors for containers, iterators, and functions.

“Essentially, an adaptor is a mechanism for making one thing act like another.”

There are three sequential container adaptors:

• Stack: FIFO.

• Queue: LIFO.

• Priority_queue: Prioritises based on, by default, <.

As an example; the stack adaptor turns a sequential container, other than array or forward_list, and makes it operate like a stack. Iterator adaptors include such things as reverse_iterator, move_iterator, http://en.cppreference.com/w/cpp/iterator#Iterator_adaptors, and stream iterators ...
