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:

1. Problem specification: formulate the problem.

2. Analysis: determine the inputs, outputs, variables, etc

3. Algorithm 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 (.c).

Just indicate here the name of the file. DO NOT paste your code into your report.

5. Testing: explain how you have tested and verified your C program.

Things to note:

1. Submit only what is required.

2. Include clear comments in your code to make it easy to understand.

3. Use the C90 standard.

4. 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.
