Assignment 1 Addendum

Queries

If you have a question about the assignment, please post it to the UTS Online forum

for this subject so that everyone can see the response.

If you have a problem such as illness which will affect your assignment submission,

please contact the subject coordinator as soon as possible.

Dr. Nabin Sharma

For frequently asked questions a FAQ file will be put up on UTS Online discussion

forum. Please check this before posting your question to UTS Online.

If serious problems are discovered the class will be informed via an announcement

on UTS Online. It is your responsibility to make sure you frequently check UTS

Online.

PLEASE NOTE: If the answer to your questions can be found directly in any of the

following

• subject outline

• assignment specification

• UTS Online FAQ

• UTS Online discussion board

• Online math equation solver websites

You will be directed to these locations rather than given a direct answer.

Assignment Errata

It is possible that errors or ambiguities may be found in the assignment

specification. If so, updates will be placed on UTS Online and announcements

made regarding the amendment. It is your responsibility to keep up to date on such

amendments and ensure you are using the latest version of the Assignment

Specification.

Assignment Submission

You must upload a zip file of the C# solution to UTS Online. This must be done by

Due Date. You might submit as many times as you like until the due date. The final

submission you make is the one that will be marked. The solution must compile

under Visual Studio 2015 or 2017. If you have not uploaded your zip file within 7

days of the Due Date, or it cannot be compiled and run on Visual Studio 2015 or

2017, then your assignment will receive a zero mark.

Acceptable Practice vs Academic Malpractice

• Students should be aware that there is no group work within this subject. All work

must be individual. However, it is considered acceptable practice to adapt code

examples found in the lecture notes, labs and the text book for the assignment.

Code adapted from any other source, particularly the Internet and other student

assignments will be considered academic malpractice. The point of the

assignment is to demonstrate student understanding of the subject material

covered. It's not about being able to find solutions on the Internet.

You should also note that assignment submissions will be

checked using software that detects similarities between

students programs.

• Participants are reminded of the principles laid down in the

“Statement of Good Practice and Ethics in Informal Assessment” in the Faculty

Handbook. Assignments in this subject should be your own original work. Any

collaboration with another participant should be limited to those matters

described in the “Acceptable Behaviour” section. Any infringement by a

participant will be considered a breach of discipline and will be dealt with in

accordance with the Rules and By-Laws the University. The Faculty penalty for

proven misconduct of this nature is zero marks for the subject. For more

information, see http://wiki.it.uts.edu.au/start/Academic_Integrity

Assignment 1 – Spring 2018 3 out of 4

Assessment

Marks will be awarded based upon the following criteria:

• Functionality: 16 marks

Your code will be run against 16 test cases. These test cases are distributed

as stated in the marking table below. For 100%, your program should pass

all test cases in all four marking tiers in the table below, as well as well

satisfying the Design and Coding Style sections below.

Only equations that maintain whole integer values throughout calculations

will be tested during marking. E.g. “X = 5 / 2” will not be tested.

The C# project must unzip successfully and compile without errors. Marks

will be deducted for compile and runtime errors.

Max Marks Functionality

16 marks

(up to 100%

total mark)

(3 test cases,

1 mark each)

The full functionality specified in the assessment specification document

including all of the below marks as well as the handling of:

• Linear (X) equations.

• Resolving multiple concurrent operators. E.g. “X = 14 - - - 8X + 4”

• Resolving multiplication through parenthesis. E.g. “4 = 2 ( X – 3 )”

13 marks

(up to 88%

total mark)

(3 test cases,

1 mark each)

A detailed integer linear equation calculator with the functionality stated

below as well as handling:

• Linear equations with multiple X variables potentially on both sides

of the = sign. E.g. “X = 2 + 3X”, “2X = 4X - 12) and “24 = 6X / 3X”

• Modified order of operations through single layer parenthesis (i.e.

no nested parenthesis). E.g. “X = (5 + 3) / 2”. This does not need to

handle multiplication through parenthesis, e.g “5 = 3(X+2)”

10 marks

(up to 76%

total marks)

(3 test cases,

1 mark each)

A simple integer linear equation calculator with the functionality stated

below except that it should handle:

• Linear equations with a single X variable on the right side of the =

sign. E.g. “24 = 6X / 8” and “6 / 3 = 5 + 3X”

• Equations that contain one or more number(s) and operator(s) on

the left of the = sign such as those seen above, including the likes of

“6 + 10 / 2 = X”.

• Invalid Input errors when no X variable or = sign is present.

• All other conditions regarding operators, parenthesis, negative

numbers, whole integer results, and error handling below are

maintained.

7 marks

(up to 64%

total marks)

(7 test cases,

1 mark each)

A simple integer calculator including the handling of:

• Only simple equations where X is always on the left of the = sign by

itself. E.g. “X = 5 + 22 * 3” should be handled. “3X = 5”, “5 = 3X”, “5 +

3 = X” do not need to be handled.

• Only fundamental operators (+, -, *, /) and no parenthesis. Order of

operations should be adhered to.

• Only equations in the form of: number > operator > number >

operator > etc. Thus, there are no two operators in a row.

• Only negative numbers at the start of the equation. E.g. “X = -6 + 3”

Assignment 1 – Spring 2018 4 out of 4

should be handled but not “X = 3 + -6”. Equation solutions may be

negative numbers.

• Removal of blank space between symbols and numbers.

• Out of Integer Range errors.

• Division by Zero errors.

PLEASE NOTE: Your final submission to UTS Online is the one that is

marked. It does not matter if earlier submissions were working; they will be

ignored. Download your submission from UTS Online and test it thoroughly in

your assigned laboratory.

PLEASE NOTE: Your final submission will be tested against the latest version

of the assignment specification and benchmark. It is your responsibility to

ensure you keep up–to-date with any amendments that may occur.

• Design: 6 marks

Marks will be awarded on the quality of your code design and the algorithms

used. This includes splitting your code up into well designed classes and

methods as bellow:

- Functional separation: Is the problem broken down into meaningful

parts and reusable methods?

- Loose coupling: Can parts be changed in isolation of each other?

- Extensibility: Would it be easy to add more functionality? (more

operations, more numerical accuracy, interactivity, variables, etc)

- Control flow: Are all actions of the same type handled at the same

level?

- Error handling: Are errors detected at appropriate places? Can they

be collected somewhere central?

• Coding Style: 3 marks

- 1 mark for consistent indentation, whitespace, and braces.

- 1 mark for appropriate and clear code comments.

- 1 mark for clear class, method, and variable naming

Assignment 1 – Spring 2018 5 out of 4

Late Assignment, Extensions and Special Consideration

Assignments that are submitted after the Due Date will lose 1 mark for each day,

or part thereof, that the assignment is late. Assignments will not be accepted

after 7 days after the Due Date.

If illness or other situation beyond your control will affect your assignment

submission or your ability to submit on time you should contact the subject

coordinator so that this can be taken into account and/or the due date extended.

Special Consideration

Students may apply for special consideration if they consider that illness or

misadventure has adversely affected their performance in the assignment. For

more information go to

http://www.sau.uts.edu.au/exams_ass/spec_cons.html

Return of Assessed Assignment

It is expected that marks will be made available 2 weeks after the demonstration

via UTS Online. You will also be given a copy of the marking sheet showing a

breakdown of the marks.

Sample Test:

Your project should be at least passed these test samples:

• X + 2 = 6

• 3X - 6 = 9

• X = 5*X – 5 * 3

• 5(2) + 5x = 15

• X / 5 = 6

• (X-2) = 0

• 4(4X) + 2(X) = 72

• 2X + 8 = 4X - 20
