Exercises and review questions

• Exercises and review questions on current lecture's material
  1. Write a singly-linked list class and implement an iterator for it.
  2. Write a program that uses the classes you wrote for the above question. This program should insert a few ints into your linked list object, and use an iterator to go through the entire list and output its contents.

• Questions on next lecture's material
