Question: 1 / 565

What is the primary reason for nesting an iterator inside a container class?

To minimize memory usage

To simplify syntax

To provide a standard interface for traversal

When creating an iterator for a container class, the primary reason for nesting it inside the container class is to provide a standard interface for traversal. By doing this, we ensure that the same syntax and methods can be used to iterate over different types of containers, making the process simpler and more consistent. Options A, B, and D are incorrect because minimizing memory usage, simplifying syntax, and reducing the need for inheritance are not the primary reasons for nesting an iterator inside a container class. These may be secondary benefits, but they are not the main purpose.
