1) Track the value of all your Pokemon cards so you can find out if your Charizard is worth more than 100 dollars

2) Keep track of customers in line at a cash register so you can deal only with the person who got in line first

3) Track the first names of everyone in the class so you can make sure your teaching examples don't use the name of someone in class

4) Track the student numbers of everyone in the class to make sure nobody is using a counterfeit duplicate number

5) Track all the books you own that begin with each letter of the alphabet so you can organize your shelves (this one is the combination of two containers)
