Behavioral Design Patterns in C++ - Containers - IV (ArrayIterator)

The video tutorial covers the implementation of an iterator in an Array class. It begins with an introduction to the Array class and the base class iterator. The tutorial then explains how to add an iterator to the Array class and implement it. A function to create an Array iterator is introduced, highlighting its necessity in the container base class. The video concludes with a demonstration of using the iterator in the main function and a preview of adding an iterator to the List class in the next lecture.

What is the purpose of the Has Next function in the iterator implementation?

• To sort the elements in the array

• To remove elements from the array

• To add elements to the array

• To check if there are more elements to iterate over

Where is the implementation of the iterator added in the Array class?

• In the main.cpp file

• In the array.hhero file

• In the array.cpp file

• In the iterator.cpp file

What are the two attributes required for the iterator in the Array class?

• A pointer to the start and a pointer to the middle

• A pointer to the array and a size variable

• A pointer to the array and a pointer to its end

• A size variable and a capacity variable

What is the purpose of using a covariant return type in the create iterator function?

• To simplify the function signature

• To enable overloading of the function

• To allow returning a more specific type

• To make the function private

What is the next step mentioned for the iterator implementation?

• Adding iterator to the list class

• Optimizing the current iterator

• Removing iterator from the array class

• Documenting the iterator code
