Create a class hierarchy to be used in a university setting. The classes are as follows: The base class is Person. The class should have 3 data members: personID (integer), firstName(string), and lastName(string). The class should also have a static data member called nextID which is used to assign an ID number to each object created (personID). All data members must be private. Create the following member functions: o Accessor functions to allow access to first name and last name...

Overview This checkpoint is intended to help you practice the syntax of operator overloading with member functions in C++. You will work with the same money class that you did in Checkpoint A, implementing a few more operators. Instructions Begin with a working (but simplistic) implementation of a Money class that contains integer values for dollars and cents. Here is my code: /********************* * File: check12b.cpp *********************/ #include using namespace std; #include "money.h" /**************************************************************** * Function: main * Purpose: Test...

An array of class objects is similar to an array of some other data type. To create an array of Points, we write Point parray [4]; To access the object at position i of the array, we write parray [i] and to call a method on that object method, we write parray [i]. methodName (arg1 , arg2 , ...) ; To initialize an array of objects whose values are known at compile time, we can write Point parray [4] =...
