You will be writing a program that reads multiple text files in parallel by using threads along with mutex and calculating the student's participation score. See attached: Roster.txt 1.txt (sample file, a number of files is provided by the user input) Participation class (see skeleton below) The following ADT variable should be made available to all threads through a globally accessible ChatParticipation instance. Thus, all variables are allocated within a class and each thread should access to it by calling appropriate getter and setter functions. Implement required functionality for this ADT skeleton code. class Participation { private: int size; //size of the roster string * names; // a pointer to a dynamic array with the names in the roster file int* participation Points; lla pointer to a dynamic array with the size of the roster. It stores participation points for each student. Example, Anna has 50 chats in all text files, thus participation Points[0]=50. int totalSum;lla variable to store a total number of all student messages in all chat files double * scores; lla variable to store the outcomes, max score is 100. Assign a participation score to each student based on their participation points. Example, calculate an average for class participation points, suppose the class average is 45, and Anna has 50, thus scores [0]=100. Otherwise, the score needs to be adjusted /prorated. public: Participation () { I/TODO: allocate dynamic arrays } I/TODO: getter, setter, destructor methods } ChatParticipation; //global variable. All threads can access it. //This function header needs to stay the same. void *do_work(void *argX /* TODO: This user-defined function is used by each thread accessing the unique data file (example: 1.txt 2.txt and so on). The result from this function is written into the private total sum variable and participation Points. Since the threads will need to modify the shared variables within the class, you are required to use the mutex variable for race condition prevention. */ } The main program will ask for user for input for how many text files are available; then your program needs to populate the dynamic array of student names, listed in the Roster.txt The main program shall also create a dynamic number of threads which preform calculation of participation Points and totalSum by using the same do_work function. The main thread needs to wait for all threads to finish and then calculate scores, and output the values in the following format: Student Name/Participation Points/Score.
