Generalization or specialization hierarchy: The arrangement of higher-level supertypes entity and lower-level subtypes entity is called as generalization or specialization hierarchy. The specialization hierarchy is a “is-a” relationship model. It contains many levels of subtype or supertype relationships. Subtype is related to an entity supertype, where the supertype entity has common characteristics and the subtype entity has the unique characteristics of each entity subtype.

Question

Chapter 6, Problem 26E

Program Plan Intro

Generalization or specialization hierarchy:

The arrangement of higher-level supertypes entity and lower-level subtypes entity is called as generalization or specialization hierarchy.

The specialization hierarchy is a “is-a” relationship model.

It contains many levels of subtype or supertype relationships.

Subtype is related to an entity supertype, where the supertype entity has common characteristics and the subtype entity has the unique characteristics of each entity subtype.

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…
