## Iterator ( )

Default constructor.
## Iterator ( const Iterator & it )

Copy constructor.
### Arguments

- *const Iterator &* **it** - Iterator.

## int operator!= ( const Iterator & it ) const

Check if two iterators are not the same.
### Arguments

- *const Iterator &* **it** - The second iterator.

### Return value

1 if iterators are not the same; otherwise 0.
## int operator!= ( const typename Tree < Key, Data >::ConstIterator & it ) const

Check if two iterators are not the same.
### Arguments
