Question

What are Iterators in C++?

Answer 1

From p. 80 of Accelerated C++:

An iterator is a value that

• Identifies a container and an element in the container
• Lets us examine the value stored in that element
• Provides operations for moving between elements in the container
• Restricts the available operations in ways that correspond to what the container can handle efficiently
