Add the following functions: (1) change when the customer pays more than the price of the purchased beverage; (2) return the customer's payment if the purchased beverage has been sold out, otherwise, it will be sold normally. Draw a complete sequence diagram showing the above functions.

Programming cannot exist without the use of selection structures, however these structures are not without flaws. Because of the large number of users, online customers, and diverse types of transactions, each application must follow the same iterative method. Are those working in these fields required to comply by a certain code of ethics? What exactly is it that sets these constructions apart from others?
In class we did the exercise of writing the IPO diagram for determining the tip and tax for a restaurant bill.
