More About Iterators
Ray Lischner · Apress eBooks · 2020
Iterators provide element-by-element access to a sequence of things. The things can be numbers, characters, or objects of almost any type. The standard containers, such as vector , provide iterator access to the container contents, and other standard iterators let you access input streams and output streams, for example. One way to think of a range is as a pair of iterators. Standard algorithms require iterators for operating on sequences of things.
