Multiple Inheritance
Can someone help me on this question? The following class diagrams are designed for a restaurant that also provides home delivery services. Study the given class diagrams, additional information and answer questions that follow:
HomeMeal
address: string
HomeMeal(string, string, double, int, double)
showHomeMeal():void
Split into class DineInMeal and HomeDelivery
DineInMeal
mealSet: string
price: double
DineInMeal(string, double)
showDineInMeal():void
HomeDelivery
district: int
deliveryFee: double
HomeDelivery(int, double)
showHomeDelivery():void
Additional Information:
1.showDineInMeal() Uses cout to display its respective data members
2.showHomeDelivery() Checks the home delivery district. If it is 123, the delivery
fees is $5, if it is 135, the fees is $10, otherwise the delivery
fees is $20. Set the deliveryFee accordingly.
3.showHomeMeal() Uses cout to display its respective data members. Invokes
showDineInMeal() and showHomeDelivery(). The total charge is the sum of price and deliveryFees. Display the total charges.
(a) Recognize the value of inheritance and using C++ code, construct the class
specification for:
(i) Base classes: DineInMeal and HomeDelivery
(ii) Derived class: HomeMeal
(b) Develop C++ code to implement the constructor and methods found in the:
(i) Base classes: DineInMeal and HomeDelivery
(ii) Derived class: HomeMeal
(c) Write a test driver to test the following requirements with the given test data.
Use the following test data to instantiate TWO instances of HomeMeal
Invoke the method, showHomeMeal()
Delivery Address Meal Set Price District Delivery Fees
123 Thomson Close Dinner Premium Set A 123.50 450 20.00
45 Scotts Road Dinner Super Premium Set A 450.00 123 5.000
