Textbook Question
Chapter 17, Problem 17.22E
(Time Class Modification) It would be perfectly reasonable for the Time class of Figs17.4–17.5 to represent the time internally as the number of seconds since midnight rather than the three integer values hour, minute and second. Clients could use the same public methods and get the same results. Modify the Time class of Fig17.4. to implement the time as the number of seconds since midnight and show that there is no visible change in functionality to the clients of the class. [Note: This exercise nicely demonstrates the virtues of implementation hiding.]

(Composition) Write a Pizza class so that this client code works. Please note that it is ok if the toppings are listed in a different order.
>>> pie = Pizza()
>>> pie
Pizza('M',set())
>>> pie.setSize('L')
>>> pie.getSize()
'L'
>>> pie.addTopping('pepperoni')
>>> pie.addTopping('anchovies')
>>> pie.addTopping('mushrooms')
>>> pie
Pizza('L',{'anchovies', 'mushrooms', 'pepperoni'})
>>> pie.addTopping('pepperoni')
>>> pie
Pizza('L',{'anchovies', 'mushrooms', 'pepperoni'})
>>> pie.removeTopping('anchovies')
>>> pie
Pizza('L',{'mushrooms', 'pepperoni'})
>>> pie.price()
16.65
>>> pie2 = Pizza('L',{'mushrooms','pepperoni'})
>>> pie2
Pizza('L',{'mushrooms', 'pepperoni'})

Modify the Show class such that it implements the Comparable interface of java.lang. Remember to add the concrete type Show between <> when you implement Comparable. Note the syntax error that occurs and understand why it occurs. 2. Implement (override) the compareTo method in the Show class such that it compares the showsaccording to their rates: returns 1 if the first show’s rate is greater than the second, -1if the first show’s rate is less than the second, and 0 if they are equal. (First show is “this”, second show is o) 3. Define an interface named Ratable, that has the method updateRate as shown in the UML diagram, in a file named Ratable.java. 4. Modify the Show class such that it implements the Ratable interface. Note the syntax error that occurs in the updateRate method and understand why it occurs. 5. Modify the updateRate method in the Show class such that it returns a double value that represents…

- Solve the problem in C++ (Extend MyPoint) In Programming Exercise 9.4, the MyPoint class was created to model a point in a two-dimensional plane. The MyPoint class has the properties x and y that represent x- and y-coordinates, two getter functions for x and y, and the function for returning the distance between two points. Create a class named ThreeDPoint to model a point in a three-dimensional space. Let ThreeDPoint be derived from MyPoint with the following additional features: - A data field named z that represents the z-coordinate.- A no-arg constructor that constructs a point with coordinates (0, 0, 0).- A constructor that constructs a point with three specified coordinates.- A constant getter function that returns the z value.- A constant distance(const MyPoint&) function to return the distance between this point and the other point in the three-dimensional space.
