1. Assignment guidance
HealthMate CIC, a Community Interest Company based in the UK, is embarking on an ambitious project to
support healthy lifestyles and improve digital literacy among high achieving secondary school students.
They intend to use open-source tools and platforms like the BBC Micro:Bit (as teachers and schools already
have extensive experience of the device).
Their aim is to create a proof of concept that combines health consciousness with the teaching of digital
proficiency.
As intern software developers, you will work on the development of a step tracker data analysis tool, the
first step in this large project.
Your mission is to develop a console application in C capable of analysing step data either from a data file, or
directly from a Micro:Bit device.
This tool should offer a large range of analyses to give users detailed insights into their daily physical activity,
supporting HealthMate CIC’s vision of a digitally literate and health-conscious younger generation.
Although you will be expected to submit files to Gradescope for marking, you should continue to use Git and
Codespaces to develop your code.
If ever there are doubts whether work is completely your own, we will be able to look at your commit history
and this will be very good evidence for you to prove that there is no issue with academic integrity.
We can give you general guidance and remind you where to find relevant supporting material in the notes,
but coursework is individual and by submitting it, you are confirming that it is your own individual work.
You must attempt the part 1 task. All the part 2 tasks are optional but remember that the passing grade for
the module is 40%.

2. Assessment tasks
Part 1: Submission deadline Friday November 3rd 2023, 14:00.
You have unlimited submissions attempts until the deadline.
Total marks available: 15
Task 1: Understanding our data files
Difficulty level: BRONZE
Task 1 marks: 15
You are given a data file called FitnessData_2023.csv and a code template file StepsTask1.c
Each row in the csv file looks like this:
2023-09-01,08:15,150
• The first column represents the date (in YYYY-MM-DD format).
• The second column is a time (8.15am in our example)
• The third column represents the steps counted in the 15 minutes immediately before the time stamp.
Here, it means that the step counter has counted 150 steps between 8.00am and 8.15am.
Your client wants you to write a single C program that will:
• Read in this csv file
• Store it in a suitably sized and structured array and typedef data structure
• Write the number of records in the file to the screen in this exact format (234 is just an example):
Number of records in file: 234
• Write to the screen the first three rows of the file (corresponding to the times 07:30, 07:45, 08:00).
This should be in the format:
2023-09-01/08:15/150
Note that there are NO SPACES in the output string.
In both cases, note that there is NO WHITESPACE before or after the strings. We will test for this format
EXACTLY.
The code will be marked automatically, so if your source file does not have the correct name or you get the
output wrong it is likely you will get no marks.
We will test it with multiple different files – so don’t “hard code” the output.
This will involve you using an appropriate typedef (custom data structure).
UNIVERSITY OF LEEDS | SCHOOL OF COMPUTING
typedef struct {
char date[11];
char time[6];
int steps;
} FITNESS_DATA;
The template program we supply (see Minerva) has this typedef already in it. You can either use this, or you
can create your own struct if you prefer.
Also in the template, you will see that we have already written a helper function called tokeniseRecord that
you can use to split the string representing each line from the file into three individual token strings
representing the data from the row.
You do not need to understand how this function works and should not change it in any way. This is the
same function that we have used before in our teaching sessions.
When you submit the file it should have the exact filename:
StepsTask1.c
How it will be marked:
1. The ability to read in the file we give you without any errors: 2.5 marks
2. The ability to read in another data file that you have not seen: 2.5 marks
3. Printing out the number of records in the file 2.5 marks
4. Printing out the requested rows: 7.5 marks

Part 2: Submission deadline Wednesday December 13th 2023, 14:00.
Total marks available: 85
You have unlimited submissions attempts.
Task 2: Analysing our data
Difficulty level: SILVER
Task 2 marks: 30
Following on from your initial program, you now need to expand your initial program to add some features
to analyse the data and help us understand what the data means.
Following good programming practice, you should split your program functionality into two files:
FitnessDataStruct.h – a header file containing the struct typedef and any helper functions you want
StepCounter.c – a program that contains the code and functions to solve the requested tasks
The program should provide a simple menu system and ask the user to select from the following options and
an option to quit.
A: Specify the filename to be imported (we will give you some additional files to test with). This should have
some error checking so that the program can cope with an incorrect filename and a file that is of an
unexpected format.
B: Display the total number of records in the file
C: Find the date and time of the timeslot with the fewest steps
D: Find the data and time of the timeslot with the largest number of steps
E: Find the mean step count of all the records in the file
F: Find the longest continuous period where the step count is above 500 steps
These should be printed out exactly as below:
Option Example output
A Input filename:
B Total records: 229
C Fewest steps: 2023-09-01 14:20
D Largest steps: 2023-09-01 18:00
E Mean step count: 427
F Longest period start: 2023-09-01 14:20
Longest period end: 2023-09-01 18:00
How it will be marked:
1. Providing a menu system providing options A-F and Quit: 5 marks
2. Successfully coping with an incorrect filename: 4 marks
3. Displaying the total number of records: 4 marks
4. Date and time of fewest steps: 4 marks
UNIVERSITY OF LEEDS | SCHOOL OF COMPUTING
5. Date and time of largest steps: 4 marks
6. Mean step count: 4 marks
7. Longest continuous period: 5 marksx<

Task 3: Outputting sorted data
Difficulty level: SILVER
Task 3 marks: 15
This task requires you to write a utility program to output the data file sorted by descending order of step
count (so the row with the highest step count should be at the top) in tab separated values (tsv) format.
A .tsv file differs slightly from a .csv in that the delimiter isn’t a comma (,) but a tab character. This has the
special code \t
You won’t see this if printed on the screen, it will just look like a few spaces between the values.
You will be supplied with a template file with the same tokeniseRecord helper function you used before.
Your program should:
1. Provide a menu option to specify a filename, using the prompt:
Enter Filename:
2. Process the data file (read in and sort). It should be able to cope with an incorrect filename and to
give an appropriate error message if the file is not in the correct format
3. Write out the sorted data file with the same filename (but with the file extension .tsv). The record
with the highest step count should be at the top and the record with the smallest step count should
be at the bottom. You will need to think how to deal with any records where the step counts are the
same.
If the input file is:
mydata.csv
The output file will be:
mydata.tsv
How it will be marked:
1. Providing the menu option and coping with an incorrect filename: 5 marks
2. Coping with an incorrectly formatted file (the fields in the wrong order): 5 marks
3. Creating an output file in the correct format: 5 marks

Task 4: Using the BBC Micro:Bit accelerometer as a step counter
Difficulty level: GOLD
This is an extension “stretch and challenge” task. We do not expect that all students will be able to
complete it.
Task 4 marks: 25
The BBC Micro:Bit contains a 3-axis accelerometer that you can access using the C driver library we have
used in our sessions. Accelerometers are often used in step counters.
Your task is to explore how the accelerometer works and write a C program for the Micro:Bit that will record
the steps taken for a single 5 minute interval. Your program should provide some mechanism to allow this
value to be accessed or downloaded.
This task will be assessed through a demonstration and short question and answer session with one of the
lecturers or teaching assistants. You will need to book a slot to do this face-to-face or alternatively you may
record a short (maximum 5 minute) private YouTube video and let us have the link by the final submission
date.
How it will be marked:
1. Describing how you have looked at the data from the 3 axes and decided what might represent a step
count (your experimental approach): 10 marks
2. Writing and testing a C program that records the steps for 5 minutes: 10 marks
3. Providing some mechanism to download or access the number of steps: 5 marks

Task 5: Understanding code quality
Difficulty level: BRONZE
Task 3 marks: 15
For this task you will need to complete the multiple-choice quiz in Minerva. You will have one submission
attempt at this, and you will have 60 minutes to complete and submit your answers.
You will do this in your own time, and we suggest that you should use a computer with a stable internet
connection and find a quiet place where you can complete this alone without distractions.
This is an assessment, and therefore must be completed independently. You can use any notes or online
resources you would like, but you should not be working with other students.
It has 15 questions related to good programming practice.
How it will be marked:
Each of the 15 questions is worth 1 mark.

3. General guidance and study support
Please refer to the module teaching materials in Minerva for any background support.
4. Assessment criteria and marking process
This assignment tests the Learning Objectives for this module:
Marks and feedback will be returned to you approximately three working weeks after the final submission
date.
The passing mark for the assessment is 40% and this can be gained from any task or combination of tasks.
5. Presentation and referencing
You should produce working and tested C programs, uploaded to Gradescope with plenty of comments to
explain your work. We also expect you to use meaningful variable names and for code to be indented to
make it readable.
If you use an idea in your solution that you have seen on the Web somewhere then add a comment to the
code like this:
// I based this on an idea I found here:
// https://stackoverflow.com/questions/12901021/error-in-c-file-handling
If you use a book or a printed resource then give the author and title:
// I based this on an idea I got from here:
// An Introduction to C and GUI Programming by Simon Long, pages 56-57
If you used ChatGPT, the tell us the prompt you used:
// I based this on a discussion with ChatGPT
// Prompt: Explain how to import a CSV file in C
6. Submission requirements
All code should be uploaded to the submission points in Gradescope (we will explain fully how to do this in
our sessions).
7. Academic misconduct and plagiarism
Leeds students are part of an academic community that shares ideas and develops new ones.
UNIVERSITY OF LEEDS | SCHOOL OF COMPUTING
You need to learn how to work with others, how to interpret and present other people's ideas, and how to
produce your own independent academic work. It is essential that you can distinguish between other
people's work and your own, and correctly acknowledge other people's work.
All students new to the University are expected to complete an online Academic Integrity tutorial and test,
and all Leeds students should ensure that they are aware of the principles of Academic integrity.
When you submit work for assessment it is expected that it will meet the University’s academic integrity
standards.
If you do not understand what these standards are, or how they apply to your work, then please ask the
module teaching staff for further guidance.
By submitting this assignment, you are confirming that the work is a true expression of your own work and
ideas and that you have given credit to others where their work has contributed to yours.
