Question

I have a question in this homework:

At the conclusion of this programming assignment, participants should be able to:

REQUIREMENTS:

The intent of this assignment is to review concepts from your prior “CS 1” course and to challenge and enhance those concepts.

Fitbit is a company that builds wearable technology devices that track various activities. The devices have sensors that measure number of steps and distance walked, heart rate, sleep quality, floors climbed, and calories burned. In this assignment, you will analyze data that was generated from a Fitbit devices. The data is stored in a comma-separated values (.csv) file that you will find at: http://eecs.wsu.edu/~aofallon/cpts122/progassignments/FitbitData.csv. The entries in this file were merged from two different devices. You will need to filter any data that is not related to the target patient. The first data entry in the file contains the target. You will also need to dedupe any entries that appear multiple times and perform data cleansing any entries that have missing fields. A .csv file stores data as plaintext in tabular form. Each row in the file is considered a record. Each record consists of fields separated by commas.

In particular, you will analyze 24 hours of data. Each record in the “FitbitData.csv” represents one minute of data and consists of eight fields. These include the following:

Patient ID

Minute

Calories

Distance (in miles)

Floors

Heartrate

Steps

Sleep level

What data structures are required?

In this assignment, you must define a C struct to store a subset of the Fitbit data fields as follows:

typedef struct fitbit

{

char patient[10];

     char minute[9];

     double calories;

     double distance;

     unsigned int floors;

     unsigned int heartRate;

unsigned int steps;

Sleep sleepLevel;

} FitbitData;

The type Sleep is enumerated and must be defined as follows:

typedef enum sleep

{

     NONE = 0, ASLEEP = 1, AWAKE = 2, REALLYAWAKE = 3

} Sleep;

You must also define an array of FitbitData that can store 24 hours of minute data. Hence, you must declare an array of size 1440. You have the freedom to decide on other data structures and variables that you need for the assignment.

What are the other requirements?

This program does not require any user input! However, you will need to display some results to the screen!

You must open “FitbitData.csv” for mode read; check for success

You must read each record in the file as a string, one line at a time; if the record does not belong to the target patient, then it should be discarded

You must parse each record into the corresponding fields, and store into the FitbitData array; note: not all fields have values, some are “empty” or null; if some of the fields are “empty” or null, then you must perform data cleansing and insert values to construct a record that is consistent with the others; the data inserted should not represent valid values

You must compute the total calories burned, distance walked in miles, floors walked, and steps taken

You must compute average heartrate over the 24 hour period

You must report the max steps taken in one minute over the 24 hour period; if there are multiple minutes throughout the day where the max is discovered, then report the one that is the latest in the 24 hour period

You must report the longest consecutive range of poor sleep; a range is defined as one or more consecutive minutes where the sleepLevel > 1; the poorest sleep is not based on the length of the range, but the sum of the sleep levels in the range; the max sum of the ranges is considered the poorest sleep (report the starting and ending minutes of range)

You must open “Results.csv” for mode write; this will either create a new .csv or overwrite an existing one

You must output two lines to “Results.csv” and to the screen in the following format:

Line 1: Total Calories,Total Distance,Total Floors,Total Steps,Avg Heartrate,Max Steps,Sleep

Line 2: valueCalories,valueDistance,valueFloors,valueSteps,valueHeartrate,valueMax,valueSleepStart:valueSleepEnd

Lines 3 – N: the filtered, deduped, and cleansed data in the original FitbitData.csv format

You must close “FitbitData.csv” and “Results.csv”

IV. Submitting Assignments:

Using the OSBLE+ MS VS plugin, please submit your solution. Please visit https://github.com/WSU-HELPLAB/OSBLE/wiki/Submitting-an-Assignment for more information about submitting using OSBLE+.

Your project must contain at least one header file (a .h file), two C source files (which must be .c files), and a local copy of the .csv file.

Your projects must build properly. The most points an assignment can receive if it does not build properly is 65 out of 100.

V. Grading Guidelines:

This assignment is worth 100 points. Your assignment will be evaluated based on a successful compilation and adherence to the program requirements. We will grade according to the following criteria:
