Assessment Overview
This assessment aims to test your ability to design a modular program which makes use of
files and structures. Application of the software development process (SDP) is also under
assessment; the five main steps of the software development process are:
1. Problem statement: formulate the problem.
2. Analysis: determine the inputs, outputs, variables, etc.
3. Design: define the list of steps (the algorithm) needed to solve the problem.
4. Implementation: the C code has to be submitted as a separate file. Just indicate here the
name of the file.
5. Testing: explain how you have tested and verified your C program.
EXERCISE
An entertainment company designs a game: both of the player and the computer generate a
letter taking the value A, B, C, where the game result is determined by the following rules: A
< B, B < C and C < A. It would now want you to develop this software to provide players of
the game with their own secured account in which their game history including the win, lose
or draw numbers is recorded and stored in a file. There are a number of requirements as
described in the following section.
Program Requirements
Your program should provide users with the ability to create an account. An account
should be a structure type variable containing: a username, a password and a record of
the game history.
The game history should be stored in a two-dimensional array and contain the following
details as a minimum:
(i) Number of rounds in a game;
(ii) Number of player wins;
(iii) Number of computer wins;
(iv) Number of draws;
(v) Whether or not the game was overall a win draw or loss.
All of the accounts should be stored in a data file and accessed by the program.
Once a user is logged on to the game they should be able to:
(i) Start a new game;
(ii) Review their game history;
(iii) Clear their game history;
(iv) Logout.
Normally, the use of global variables is not encouraged. Any use of global variables must
be fully justified in your report.
Ideas
Note: the following are only to provide you with ideas of how to implement the required
functionality. They do not represent the “best” or only ways to implement the functions.
All of the player accounts are structure variables and will be stored in a file. The login
process can be achieved using a single structure variable, into which each account can be read
from the file one by one, each time checking the username until you find the correct players
account. The gaming operations can then be performed using that single structure variable.
When the player finishes only this one structure needs to be written back to the file for saving.
Alternatively, you can create an array of structures in the program and read the whole file
into the array, then search the array. The game can be played using the correct element of the
array of structures. When the player finishes, the whole array can be written to the file.
Try to create your own functions to simplify the programming task.
Consider how your program should function when there is an invalid input.
To make your program more interesting for the user think about what kind of information

they may like to access for example overall win percentages.
What should be submitted?
You should submit the followings:
1) Your C source code (.c) file and a short report (up to a few pages of text):
a) SDP steps 1 to 3 in the report (Problem statement(10%) + Analysis(10%) + Algorithm
Design(10%) + Report Quality(10%)) (40%)
b) SDP step 4 (Implementation(35%) + Robustness(10%)): your C source code including
the comments. (45%). Do not paste the code into your report just submit the .c source
code file and write the file name in your report under the implementation section.
c) SDP step 5 in the report (testing): you will explain your testing methodology
including: what you wanted to test, how you have tested it and the outcome of your
tests. (15%). Note: you do not need to include screenshots of all testing results. You
can include some to show correct operation and or failures, but avoid including pages
and pages of screenshots for every test you perform.
Please refer to the file “EEE101 Marking Guidelines Assignment 3” for the
detailed marking scheme.
2) The report in Microsoft Word or pdf format and C source code of your implementation
should be zipped into a single file, i.e. the zip file will contain 2 files, one document and
one source code. (It is a good practice to include comments in your code stating the aim
of the program, what are the inputs, what are the outputs, which algorithm is used, who is
the author and so on.)
The naming of Report (.docx or .pdf), Source Code (.c) and Compressed file (.zip or .rar)
StudentID_LastName_FirstName_AssignmentNumber.docx or .pdf
StudentID_ AssignmentNumber.c
StudentID_LastName_FirstName_AssignmentNumber.zip or .rar
For example
123456789_Einstein_Albert_3.docx
123456789_3.c
Zipped together into:
123456789_Einstein_Albert_3.zip
How the work should be submitted?
Should be submitted electronically through ICE so that the marker can run your programs
during marking. Feedback and your grade will also be given through ICE.
Remember that you are responsible for ensuring that your C code will run in Visual Studio
2013 and that if it does not without documentary explanation you may get a 0 mark for your
implementation.
