You are contracted to complete the data system for Citywide Taxi Company. Now, the information for each taxi is expanded to include: taxi id (such as CTC0001), the driver’s name, the maker of the Car (such as Ford), the model of the car (such as Escape), the Color of the Car (such as Black), the license number (such as HXT 4578), the number of passages the car served in the entire shift (integer type, this field will be left empty for this project). Your C++ program will (with array of class object):  

1. Define a class for the car with all members of variable mentioned above as private; (20 points)
2. Write all necessary class member functions to access those member variables (write or read); (40 points)
3. Read up to 50 records of data from the keyboard (provide a method to end the input before reaching 50 records); (10 points)
4. Save all records inputted from step 3 to a disk file called CTC.dat. (30 points)

A publication company that markets both book and audiocassets versions of its works.
create a class called publication that stores the title (a string) and price (type float) of
publication. This class includes getdata() and showdata() member functions for input and output
data members. This class also includes a pure virtual member function “ISOversize()”. From this
class derive two classes: Book, which has a page count (type int) and Tape class which has a
playing time in minutes (type float). Each of these two derived classes should override the base
class member functions. Let’s say that a book with more than 500 pages, or a tape with a
playing time longer than 90 minutes, is considered oversize. You can access member functions
from main() and display the string “Oversize” for oversized books and tapes when you display
their data.
Write a main() program that creates an array of pointers to publication. In a loop, ask the user
for data about a particular book OR tape.

His assignment is the next step to enhance your Programming Project 1 and Homework 3 works. As for 
now, you can keep the inventory in a file and upload it to the array available for your program. You have 
three classes for each type of products. It is time to think about how to improve the data model – all 
three types have enough in common to be child classes of one parent class.
Thus, the first thing to do is create a superclass and make three product type classes subclasses. Then, 
move as many members (fields and methods) from Type X, Y, and Z product classes to a superclass as 
possible. Change the constructors appropriately. 
The advantage of inheritance is the ability to create an array of superclass objects to be filled with 
objects of different subclasses. Thus, your inventory is in one array. Use the product’s index in the array 
to build the product’s ID (I would recommend starting with 1). In the superclass, create a static variable 
that holds the number of products available in the inventory. It must grow as reading from the file 
progresses.
Override a default toString() method for a superclass such that it shows product ID, name, regular 
price, and type.
At this moment, make sure that all modifications you have made keep your application alive and 
working.
The next step is to add three new classes to the project: 
• Create a class to represent the user – hardware store customer. You must decide what members 
this class needs. Ask the user to input necessary information.
• You may notice that the date of the year is a complicated piece of data. Create a class Date that 
converts a string of the form of “mm/dd/yyyy” into an object with three fields – month, day, and 
year. The class constructor may do this job, but do not forget to check the string for correctness.
Once you have this class ready, input the date as a string with the following converting into an 
object of type Date. Remember, if you read a string from the keyboard after a number, you 
may need to handle the new line symbol left in the input buffer.
• The result of your application is an order that must have the customer’s information, the date, 
the product information, and the total amount to pay. Thus, the third class to add is the class 
Order. When all the information is collected, the order is ready to be created and printed out. 
Outputting the order is the primary behavior of an object of type Order, and it is the final step 
of your application. Thus, class Order aggregates the customer’s info, date, product info, and 
total. Please note that Type X and Type Y products need only regular price and amount to 
calculate the total, while Type Z products must also consider the date.
The input and output examples for Types Y and Z are

Program requirements
The program must have one superclass and three subclasses for three types of products according to 
the description given in Programming Project 1. 
The program must read the inventory from the file into one array for all three types of products. Each 
element of the array must be an object of one of the subclasses according to the information in the file. 
Product ID must be formed automatically using a static variable.
The user must be registered in the system, and the corresponding object must be created. Then, the
user chooses a product from the list, specifies an amount and the date of planned purchasing.
The date, user, product, amount, and the total must be aggregated in an object of type Order and 
outputted.
For this assignment, it is sufficient to output the order to the console. However, additional saving the 
order in the file will be considered as a plus.
The test plan must be developed for the program. Consider and test different inputs that may cause 
errors: incorrect file records, wrong date format, invalid user’s choice.
You have four weeks and three submission attempts for this assignment. Here is the suggested scenario 
on how to plan your work:

Problem: Meal gift card. Your favorite campus restaurant sells meals for $13 each meal. The restaurant requires members to pre-pay any amount of money they wish, and then purchase as many meals accordingly. You are required to write a java program correctly that would ask the user for the amount that they will pay, then display a message indicating how many meals that user will be able to purchase as well as how much funds will remain in the gift card after that. 

Using exactly 1 integer constant, 3 integer variables, and 1 Scanner variable make sure to fulfill the following points:

1. Declare the following constant integer: PRICE and set it to 13.

2. Declare 3 unassigned integer variables amount, meals, balance.

3. Declare 1 Scanner variable that will record keyboard inputs.

4. Prompt the user in the console for the amount that they will pay and assign to amount (use same format and wording as in the sample outputs below). Assume the user will enter an integer value.

5. Assign to meals the result of amount / PRICE.

6. Assign to balance the result of amount % PRICE.

7. Output to the console a blank line followed by the message

With $ you can buy meals and will have a balance of $.

Where ,and are the values stored in the corresponding variables. 

Based on the previous specifications your program should look and behave exactly as displayed in the cases below. Your
program should work for any double values entered by the user, not just the ones in the sample.
Note that ◦ symbol indicates a space and ↵ is a new line character. All words except for user input (in blue) must be exactly as indicated in the sample. Any extra “spaces” and/or “new lines” will be graded a wrong answer.

Note 1: You are to expect a perfect user who always enters integer numbers., do not verify the validity of user input.
Note 2: The use of libraries other than java.util.Scanner is prohibited. Your program must work for any integer values entered, not just the ones in the samples above.
Note 3: Final thought, remember that your solution is space-sensitive and fulfill the above instructions carefully and
precisely.
