Question

Write a program for a retail store. The program will use three classes to identify and store the characteristics of its different customers.

This three classes will include a base class and two derived classes.

Design a base class named PersonData_C which will have member variables for last name, first name, and zip code. These three variables must be declared private.

The PersonData_C class will contain the appropriate constructors, getters and setters, and a virtual member function named Display_Data which will display the last name. first name, and zip code.

The CustomerData_C class (derived from PersonData) will have two member variables: customerNumber will be used to hold a unique integer for each customer, and mailingList will be a bool which is set to true if the customer wishes to be on the mailing list and false if not.

The CustomerData_C class will override virtual function Display_Data, and this version will display the customer number and mailing list code plus the PersonData_C class data.

Also write the appropriate constructors, accessor and mutator member functions for this class.

The retail store has a "preferred customer plan" in which customers may earn discounts on all their purchases. The amount of a customer's discount for a current purchase is determined by the amount of the customer's prior cumulative purchases in the store:

-after customers spend $500 (not including current purchase), they get a 5% discount on the current and all subsequent purchases.

-after customers spend $1,000 (not including current purchase), they get a 6% discount on the current and all subsequent purchases.

-after customers spend $1,500 (not including current purchase), they get a 7% discount on the current and all subsequent purchases.

-after customers spend $2,000 (not including current purchase), they get a 10% discount on the current and all subsequent purchases.

Write a PreferredCustomer_C class (derived from CustomerData_C) which will have two member variables: purchasesAmount will hold the total of a customer's purchases to-date, and discountLevel should be set to the correct discount percentage based on the purchasesAmount and the store's "preferred customer plan" described above (note: whenever the purchasesAmount is updated, the discountLevel must be re-calculated).

This class will override virtual function Display_Data, and this version will display the purchase amount to-date and discount level plus the CustomerData_C class data and the PersonData_C class data.

The PreferredCustomer_C class will also need the appropriate constructors, setters, and getters, and a member function to purchase items, i. e., spend money, which will add to the purchase amount to-date (after discount, if any).

In main create a CustomerData_C object using constructor arguments customer number: 987654 and mailing list code: true, and first and last name: Norton Orton, and zip code: 56789.

Then in function Display_Customer_Info with a base class reference variable as a parameter, use the virtual function Display_Data to display this object’s data items (screen print this display).

In main, create a PreferredCustomer_C object using the default constructor, then have the user enter the following data and store it in the object:

-last name: McDaniels

-first name: McDougal

-zip code: 10001

-customer number: 222222

-mailing list: 1 (true)

-purchase amount to-date: $2000.00

Have this preferred customer make a $1,000 purchase (entered by the user), and in the function with the base class reference variable as a parameter, use the virtual function Display_Data to display the information stored in the PreferredCustomer_C object's 7 data items (screen print the data entry and this display).

void main()
{
struct date
{
int day;
int month;
int year;
};
struct details
{
char name[20];
int price;
int code;
int qty;
struct date mfg;
};
struct details item[50];
int n, i;

printf("Enter number of items:");
scanf("%d", &n);
fflush(stdin);
for (i = 0; i < n; i++)
{
fflush(stdin);
printf("Item name: ");
scanf("%s", item[i].name);
fflush(stdin);
printf("Item code: ");
scanf("%d", &item[i].code);

}
printf(" ***** INVENTORY ***** ");
printf("---------------------------------------------------------

printf("S.N.| NAME | CODE | QUANTITY | PRICE

printf("---------------------------------------------------------

for (i = 0; i < n; i++)
printf("%d %-15s %-d %-5d %-5d
%d/%d/%d ", i + 1, item[i].name, item[i].code, item[i].qty,
item[i].price, item[i].mfg.day, item[i].mfg.month,
item[i].mfg.year);
