The following is code for a disc golf program written in C++:   // player.h #ifndef PLAYER_H #define PLAYER_H   #include <string> #include <iostream>   class Player { private:     std::string courses[20]; // Array of course names     int scores[20];          // Array of scores     int gameCount;          // Number of games played   public:     Player();               // Constructor     void CheckGame(int playerId, const std::string& courseName, int gameScore);     void ReportPlayer(int playerId) const; };   #endif // PLAYER_H   // player.cpp #include "player.h" #include <iomanip>   Player::Player() : gameCount(0) {}   void Player::CheckGame(int playerId, const std::string& courseName, int gameScore) {     for (int i = 0; i < gameCount; ++i) {         if (courses[i] == courseName) {             // If course has been played, then check for minimum score             if (gameScore < scores[i]) {                 scores[i] = gameScore; // Update to new minimum…
In this assignment, you will implement a multi-threaded program (using C/C++) that will check for Prime Numbers and Palindrome Numbers in a range of numbers. Palindrome numbers are numbers that their decimal representation can be read from left to right and from right to left (e.g. 12321, 5995, 1234321). The program will create T worker threads to check for prime and palindrome numbers in the given range (T will be passed to the program with the Linux command line). Each of the threads works on a part of the numbers within the range. Your program should have some global shared variables: • numOfPrimes: which will track the total number of prime numbers found by all threads. numOfPalindroms: which will track the total number of palindrome numbers found by all threads. numOfPalindromic Primes: which will count the numbers that are BOTH prime and palindrome found by all threads. TotalNums: which will count all the processed numbers in the range. In addition, you need to have arrays…
