C++ PROGRAM Create an abstract class Customer with data members name and ID. Provide pure virtual functions discount() and TotalBillAfterDiscount(). Derive a class Loyal Customer from Customer. The class has additional attributes loyaltyLevel and CurrentShoppingBill. The loyalty bill is an integer number between 1 and 20. The loyaltyLevel of a customer is increased after every 10 shoppings from the store. The discount of loyal customer is calculated based on loyalty number and CurrentShoppingBIll, and has the formula discount = loyaltyLevel% X CurrentShoppingBill (if loyaltyLevel =15 then discount = 15% X CurrentShoppingBill). Derive another class Wandering Customer from Customer. The class has attributes shoppingNumberFromStore and CurrentShoppingBill. The discount is given to Wandering Customer if shoppingNumberFromStore is greater than 5 and CurrentShoppingBill is greater than 1500. If these two conditions are met only then the discount is given otherwise no discount is given. The discount formula for wandering customer is discount = CurrentShoppingBill x (shoppingNumberFromStore/10). TotalBillAfterDiscount() is computed as CurrentShoppingBill – discountedBill for both classes. Write a program to declare two pointers of class Customer. Create an object each of loyal and wandering customer, assign their addresses to pointers of base class, set the values of data members and call the discount and TotalBillAfterDiscount function for each.
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
C++ PROGRAM
Create an abstract class Customer with data members name and ID. Provide pure virtual functions discount() and TotalBillAfterDiscount().
Derive a class Loyal Customer from Customer. The class has additional attributes loyaltyLevel and CurrentShoppingBill. The loyalty bill is an integer number between 1 and 20. The loyaltyLevel of a customer is increased after every 10 shoppings from the store. The discount of loyal customer is calculated based on loyalty number and CurrentShoppingBIll, and has the formula discount = loyaltyLevel% X CurrentShoppingBill (if loyaltyLevel =15 then discount = 15% X CurrentShoppingBill).
Derive another class Wandering Customer from Customer. The class has attributes shoppingNumberFromStore and CurrentShoppingBill. The discount is given to Wandering Customer if shoppingNumberFromStore is greater than 5 and CurrentShoppingBill is greater than 1500. If these two conditions are met only then the discount is given otherwise no discount is given. The discount formula for wandering customer is discount = CurrentShoppingBill x (shoppingNumberFromStore/10).
TotalBillAfterDiscount() is computed as CurrentShoppingBill – discountedBill for both classes.
Write a program to declare two pointers of class Customer. Create an object each of loyal and wandering customer, assign their addresses to pointers of base class, set the values of data members and call the discount and TotalBillAfterDiscount function for each.
