std::iterator is the base class provided to simplify definitions of the required types for iterators.
Template parameters
| Category | - | the category of the iterator. Must be one of iterator category tags. |
| T | - | the type of the values that can be obtained by dereferencing the iterator. This type should be void for output iterators. |
| Distance | - | a type that can be used to identify distance between iterators |
| Pointer | - | defines a pointer to the type iterated over (T) |
| Reference | - | defines a reference to the type iterated over (T) |
