1. Implement the ADT appointment book, described in Section 1.4.1 of Chapter 1 . Write a program that demonstrates your new class.

2. Repeat the previous project to create a spell checker, but instead place the words whose spelling you want to check into a bag. The difference between the dictionary (the set or bag containing the correctly spelled words) and the bag of words to be checked is a bag of incorrectly spelled words.
