Modify the definition of the class Money shown in Display 8.5 so that the following are added:

a. The operators <, <=, >, and >= have each been overloaded to apply to the type Money. (Hint: See Self-Test Exercise 8.)

b. The following member function has been added to the class definition. (We show the function declaration as it should appear in the class definition. The definition of the function itself will include the qualifier Money::.)

For example, if purse is an object of type Money whose value represents the amount $100.10, then the call

returns 10% of $100.10; that is, it returns a value of type Money that represents the amount $10.01.
