You're writing a class that implements a stack (LIFO, Last In First Out) data structure using an array of Tally objects that can only be accessed from outside the class via a pop() and push() functions that you'll be writing.

The Stack class is implementing stack behavior using an array ( vector? ) to store the stack.  Storage is one aspect of a stack.  Adding, removing, and managing the storage are other aspects of a stack.  Therefore, the storage has an "is part of" relationship with the class.
