Assignment 2: Parallel Implementation
Overview
This assignment will test your skills in programming applications to specification in a number of different
programming languages and is worth 20% of your non-invigilated (type A) marks for this course. Completion
of this assignment requires the:
 Understanding of various programming languages’ features
 Understanding of Implementing a program in multiple languages
Timelines and Expectations
Percentage Value of Task: 20%
Due: 04:00 pm Friday the 5th June 2020 (week 11)
Minimum time expectation: 20 hours
Assignment Overview
You are asked to create a program for a pizza shop – however, as this is a comparative languages course, you will be
creating the same application in the following programming languages:
 C
 Python,
 Java and
 Lisp
As you implement the application in each language, you should keep notes on the features of the languages used, which
you found useful, as well as any issues or complications which arose due to the complexity or lack of any language features.
A brief discussion based on these programming features for each individual language accompanying each implementation
is required. Finally, a comparative overview of the languages highlighting applicability based on your experience in the
design, implementation, and debugging of your code is also required.
If you foresee or encounter any complications, you may opt to implement or incorporate additional language features that
may be lacking, i.e. data structures. This can be done via:

 Your own implementation,
 Through libraries, or
 Via the incorporation of existing source code. You can use code found on the Internet, but the use of any
existing code must be referenced.

Assessment Details
Sab, the owner of a new Pizza and Pasta shop, is opening a takeaway service for selling delicious Pizza and Pasta to the
customers. She wants to offer some packages to interested customers to promote her business. To do so she is offering
the following packages:
1. 1 large Pizza = 12 AUD
2. 2 large Pizzas = 22 AUD
3. N large pizzas = N*10 AUD, where N>=3, and the customer will receive 1 garlic bread for
every three pizzas [For example, if a customer is interested to buy 10 large pizzas, Sab
will provide 3 complimentary garlic bread for 100 AUD]
4. 1 large pasta = 8 AUD
5. 2 large pastas = 15 AUD
6. M large pasta = M*7 AUD, where M>=3, and the customer will receive 1.25 Liter soft
drinks for every 3 pasta [For example, if a customer is interested to buy 6 large pasta, Sab
will provide 2 complimentary 1.25-liter soft drinks for 42 AUD]
7. For every 3 pizzas AND 3 pasta, Sab will give a small box of Baklava (a famous dessert
item) in addition to garlic-bread and 1.5-liter soft drinks.
You have agreed to design and develop a small console program for Sab, enabling her to select the appropriate item and
the package, and calculate the corresponding cost. Once an order is processed, the program will return to the menu ready
to commence another order. This payment information should display:
 the total payment amounts received for the pizza order
 the total payment amounts received for pasta order
 the total amount of pizzas and pasta sold in that session*
*A session indicates the duration Sab is using the program after opening the program. There is no need for this data to
persist once the program has stopped running.

The owner wants the system to be flexible so that she can include additional items and packages at a later date without
having to rewrite the entire program. This means you will need to use an interface for processing payments, and
polymorphism for the various food items classes, so that new and different packages may be added at a later date with
minimal updates to the code. She asked that you provide her with some documentation before you commence coding, so
that she is able to verify that the program you intend to code will address her requirements. She would like to see the use
cases to summarize the requirements in written format, as well as use case diagrams, class diagrams and sequence
diagrams.
Suggested Development Environments
Codeblocks for C '99
Code::Blocks can be downloaded from http://www.codeblocks.org/downloads/binaries To create a new C project is: When
you create a project, choose File | New and then Console Application, and then choose C as the programming language.
IDLE for Python:
Python, including the IDLE development environment, can be downloaded from https://www.python.org/downloads/
Eclipse for Java 7 or Java 8

Eclipse may be freely downloaded from http://www.eclipse.org/downloads/
Eclipse does not come with the Java JDK, which must the downloaded separately from
http://www.oracle.com/technetwork/java/javase/downloads/index.html
Ensure that your Eclipse type and Java type match – i.e. 32-bit Java for 32-bit Eclipse, or 64-bit Java for 64-bit Eclipse. If
you mix and match it won't work.
GNU CLisp for Common Lisp

CLISP 2.49 can be sourced from http://sourceforge.net/projects/clisp/files/latest/download
Any good text editor would be suitable for writing the source code.

Additional Documentation – Language Suitability Report
The design of each programming language incorporates a number of decisions about the language which makes it more
or less suitable for given tasks. During your implementation of the pizza program in each of the languages, you should
make notes about the language features which exist or do not exist, and which have therefore made program development
easier or more difficult.
Where a language has not provided a feature which would have been useful to the implementation of the program, or where
the complexity of using a language feature has been high you should remark upon it and briefly discuss a mechanism or
feature of another language which would have made development easier.

CRICOS Provider No. 00103D ITECH5403 Assignment_2-2020-07.docx Page 4 of 6
After completing the application in all languages (or as many as you can), discuss the comparative ease of implementation
in terms of the design, implementation and debugging for each programming language, including how robustness issues
were addressed.
Submission and Marking Process
You must supply your program source code files and language suitability report documentation in a single compressed
archive called:
ITECH5403_Assignment_2__.zip
You may supply your programming language suitability report in either Word or LibreOffice/OpenOffice format in which the
document can be edited – no proprietary Mac-specific formats, please.
Assignments will be marked on the basis of fulfillment of the requirements and the quality of the work. In addition to the
marking criteria, marks may be deducted for failure to comply with the assignment requirements, including (but not limited
to):
 Incomplete implementation(s), and
 Incomplete submissions (e.g. missing files), and
 Poor spelling and grammar.

Submit your assignment (all program source files plus your discussion document) to the Assignment 2 Upload location on
Moodle before the deadline of Friday of Week 11 at 4 pm.
The mark distribution for this assignment is explained on the next page.
