CPT109 C Programming and Software Engineering 1 – ASSESSMENT 2
Assessment Number 2
Contribution to Overall Marks 50%
Issue Date 08/11/2021
Submission Deadline 06/12/2021 at 00:01
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 steps required for your SDP report are:
- Problem specification: formulate the problem.
- Analysis: determine the inputs, outputs, variables, etc
- Algorithm Design: define the list of steps (the algorithm) needed to solve the problem.
- Implementation: the C code has to be submitted as a separate file (.c).
Just indicate here the name of the file. DO NOT paste your code into your report. - Testing: explain how you have tested and verified your C program.
Things to note: - Submit only what is required.
- Include clear comments in your code to make it easy to understand.
- Use the C90 standard.
- ALL programs MUST compile and run in Visual Studio 2013.
Exercise
The game of hangman is a popular children’s word guessing game aimed at improving
spelling and general knowledge. A secret word is chosen (usually related to a chosen topic
e.g. a country or a fruit or vegetable) and the player tries to work out what the word is by
guessing letters. Each time a player correctly guesses a letter in the word, then the letters
should be filled in at their appropriate location in the word (see below). Note that the letters
can be guessed in any order. If the player guesses a letter incorrectly, then the hangman’s
gallows (See Figure 1a) are constructed one line at a time for each wrong letter till the player
dies after 8 wrong guesses. A possible text-based version of the hangman’s gallows is shown
in Figure 1b. Example game:
Secret word entered by player 1 is: Guangzhou
Displayed on the screen is: ?????????
Player 2 guesses: G
Displayed on the screen is: G???g????….and so on
Figure 1a Hangman Picture Figure 1b Possible text-based drawing
The secret word should be either entered by a second user or randomly selected by the
program from a file of words provided. Program users should create a unique password
protected account which will record their win/lose record, and which can be viewed.

Program Requirements
Allow users to create an account by selecting a username and password. The account
should be saved in a file (unique to each user), which will contain a structure with the
password and the win/lose history.
Once a user is logged in they should be able to:
Start a new game
Review their game history
Clear their game history
Logout
On starting a new game, there should be a choice either to play with a random secret
word chosen from a data file (the filename should be provided) or for another user to
enter a secret word.
The player should guess letter one at a time. After each guess either the appropriate blank
or blanks of the secret word are filled, or the next section of the picture is included, and
both the current word state and the current hangman picture are displayed.
If the player completes the word before the hangman picture is complete, they win, if the
picture is complete first then they lose.
All variables used must be local.
Programming Suggestions/Ideas
The following points 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 player accounts are structure variables and will be stored in a unique file i.e. one file
for each player account. Create new accounts by creating a new file with the username
selected. The login process can be achieved by trying to open a file, if successful the
structure stored in the file can be copied into the program memory. When the player logs
out only this one structure needs to be written back to the file.
Try to create your own functions to simplify the programming task, for example use one
function to draw the hangman picture.
Consider how your program should function when there is an invalid input.
You can design your own figure (it is your interpretation of the game).
Consider the playability, how can you make the user interaction more interesting for
example add your own rule such as do not allow vowel letters (a, e, i, o ,u), or maybe
only 1 vowel letter is allowed. You may wish to display a list of the wrongly guessed
letters as a reminder to the player
Submission
Your assessment should be submitted electronically through the Learning Mall Online
(LMO). Feedback and your grade will also be given through LMO.
Software Development Process (SDP) report (5 steps) named: studentID_A2.pdf
Sourcecode (.c) file named: studentID_A2_1.c
Data file: data.txt
This is the file containing the words to be used when playing the game against the computer
Submission should be a single compressed file containing at least 3 files:
1234567_A2_1.c
1234567_A2.pdf
data.txt
1234567_A2.zip
Compressed folder can be of type .zip, .rar or .7z
If you have multiple program files please use the following naming convention:
Sourcecode files (.c) you should number these accordingly e.g. 1234567_A2_2.c.
Header files (.h (and associated .c file), name these: 1234657_A2_H1.h
(1234567_A2_H1.c) if there are more than one number them accordingly (i.e. H1, H2..).

Please refer to the file“CPT109 Marking Guidelines for Assignment 2”on Learning
Mall for details on marking descriptions.
You are responsible for ensuring that your C code will run in Visual Studio 2013. If it does
not without documentary explanation you may get a 0 mark for your implementation.
There will be a 5% deduction for incorrectly named files in your submission.
Important notes:
University late submission policy will be applied.
University Academic Integrity policy will be applied rigorously. Plagiarism and collusion
will not be tolerated.
You can find information relating to both of these in ebridge.
