Hi John,

You need to create an instance of Account and post the transactions to 
it by calling instance methods on the account. The Account class may 
need to keep track of the individual postings as well as the total balance.

There is a lot to the assignment - is this one of your first assignments 
or a later one? Without a bit of context of where you are in the course 
it's hard to know what is expected. It sounds like you may need some 
kind of persistent storage like a database but I don't know if you have 
learned anything about that yet.
