STUDENT SCENARIO:PROGRAM DESIGN PROJECT

In this scenario, your school has decided to purchase movies for students to rent. Your assignment is to design a program

that will help your school keep track of which movies are available, which movies are rented and the student bill.

Theresa Kim will be your guide for the lesson. Your instructor will be your overall project manager and information resource.


OBJECTIVES[STILL NEED OBJECTIVES]

This course will enable you to develop logical thinking skills, including:• Asking probing questions to uncover details of a problem• Clearly defining a problem• Defining clear success criteria for the project including

measurable objectives


Hi, I’m Theresa. I’ll be your guide for this

assignment.


PROJECT OVERVIEW

You will work on this project for the entire semester adding

to the project when you learn a new design skill. You will

not design the entire project at one time. You submit one

portion of the project at a time.


Your Assignment

Create a pseudocode design for a program that

will allow students to rent movies. The system

will allow students to search the available movie

inventory, return a movie and rent a movie.

The student information is located using their

email address. After the student rents the movie,

the system will list the movies the student rented

and a bill. The student will be prompted to enter

their payment information.


The Completed System Will:

• Store student and movie information.

• Update the movie inventory. (keep an

accurate count of the number of movies

available)

• Bill a customer using the following rules:

– Students can only rent up to 3 movies

at a time

– If students rent 3 movies, they receive

1 of the three movies for free

– Each movie costs $1.50


• Billing rules (cont.):

– A 5% Sales tax is added to the

total cost.

– If the movie is rated R, the system

must verify that the student is 17

years old or older. If the student is

under 17, an error message is

printed and the movie is removed

from the student's list of movies.


Ready to get started? Your tasks are waiting for you!


TASK 1: DATA FILES

For this task, you will create preliminary data files.


Task 1 Overview

The first step is to determine the type of

input data needed for the movie check-out

system. You may learn that you need to add

more fields as you continue to work on the

problem.


Deliverables

1. Create a sample Customer data file that

includes at least 5 records

– Create headings over the columns

– Save the file as CustomerData_LastName

(where LastName is the your last name)


Deliverables (cont.)

2. Create a sample Movie data file that



– Save the file as MovieData_LastName




3. Create a sample Payment data file that



– Save the file as PaymentData_LastName



Now you’re ready to move on to the

next task.


TASK 2: BASIC DESIGN(SIMPLE SEQUENCE AND SELECTION)

For this task, you will build on your work in Task 1 and create code to prompt a student for specific data.


Deliverables

Create a pseudocode/flowchart design to

prompt a student for their Email Address

and the titles of the three movies they want

to rent. The problem should display the

Student’s email address and a total bill.

Take into account the data that you created

during Task1. Modify the files that you

create during Task 1. you need to add more

fields to the files.


Action Steps

1. Bill a student using the following

rules:

• Students can rent up to 3 movies.

• If the movie is rated R, the system must

verify that the customer is 17 years old

or older

• If the customer is under 17, an error

message is printed stating that the

customer is not allowed to rent the

movie


Action Steps (cont.)

1. Rules (cont.):

• Each movie costs $1.50

• A 5% Sales tax is added to the total cost.

2. Save the file as: Simple_Sequence_Selection_SchoolName

(where SchoolName is the name

of your school)


Good job. Let’s move on!


TASK 3: DESIGN FORMULTIPLE CUSTOMERS

(ITERATION – LOOP)

For this task, you will modify your work in Task 2 to include a loop.


Deliverables

Modify the pseudocode/flowchart design

that you created in Task 2 to include

statements to prompt the student to enter

the movie titles one movie at a time. After

the student has finished entering the

movie titles, the system will calculate and

print the bill.

Hint: use a loop to process the total bill.


Action Steps

1. Add the statement(s) for the following:

• If customer rents 3 movies, they

receive 1 of the three movies for free

2. Save the file as Iteration_SchoolName

(where SchoolName is the name of

your school)


You’re ready for your next task.


TASK 4: ORGAINZING STATEMENTS (MODULES)

For this task, you will enhance your Task 3 work with new modules.


Deliverables

Modify the pseudocode/flowchart design

that you created during Task 3 to include

at least the following modules.

• Enter Student Email

• Calculate the Bill

• Print the Bill

After the student has finished entering the

movie titles, the system will calculate and

print the bill.


Action Steps

1. Create a hierarchy chart for the

modules

2. Save the hierarchy chart as

Hierarchy_Chart_LastName (where

LastName is your Last Name)

3. Save the pseudocode/flowchart

design using the filename

Modules_LastName (where

LastName is your Last Name)


Let’s move on to Task #5.


TASK 5: ORGANIZING DATA (ARRAYS)

For this task, you will create data arrays, adding to the work you completed in Task 4.


Deliverables

1. Modify the pseudocode/flowcharting

design that you created in Task 4 to

include at least the following modules:

– Enter the MovieName into an array

named Movies and QuantityonHand

into an array named MovieQuantity

• The information for the movies is stored

in the MovieData_LastName file

• QuantityonHand = -999 when end the

file is reached)



1. Modify the pseudocode/flowcharting

design that you created in Task 4 to

include at least the following modules:

– Update Movie inventory (add to

inventory/deduct from inventory)

– Calculate and print the customer bill

– Calculate and print the total daily sales

– Calculate and print the average

number of movies rented



2. The customer will be prompted to enter

their email address and whether they

want to rent or return a movie.

3. If the student wants to rent a movie,

after the customer has finished entering

the movie title(s), the system will

calculate and print the bill.

4. If the student wants to return a movie, a

message is printed on the screen after

returning the movie(s)



5. Modify the hierarchy chart to include the

new modules. Save the hierarchy chart

as Hierarchy_LastName

6. Save the pseudocode/flowchart design

using the filename Arrays_LastName

(where LastName is your last name)


OK, you’re ready for your last task.


TASK 6: OBJECTS

For this task, you will use object-oriented design to design classes.


Deliverables: Part 1

Use object-oriented design to design a class

called Customer that will receive the

information in the Sample Customer Data

file that you created during Task 1 of the

project. The class that you create will receive

the customer data, validate the data and

display the input data.


Action Steps: Part 1

1. Design the class table

2. Write an algorithm for each operation

3. Write a test or driver algorithm to test

the solution



Use object-oriented design to design a

class called Movie that will receive the

information in the Sample Movie Data file

that you created during Task 1 of the

project. The class that you create will

receive the movie data, validate the input

data and print the valid movie data that

have a quantity amount equal to 0.



1. Design the class table

2. Write an algorithm for each operation


the solution



Use object-oriented design to design a

class called Payment that will receive the

information in the Sample Payment Data

file that you created during Task 1 of the

project. The class that you create will

receive the payment data, validate the input

data and print the data.



1. Design the class table.

2. Write an algorithm for each operation.


the solution

When you are done with Parts 1-3, save

the file as Objects_LastName (where Last

Name is your last name)
