STEP 1: Start a new C# Console Application project and rename its main class Program to ZooPark. Along with the ZooPark class, you need to create an Animal class. The ZooPark class is where you will create the animal objects and print out the details to the console. Add the...
Ship, CruiseShip, and CargoShip Classes (in C++ language i use visual studios to code with) design a Ship class that has the following members: - A member variable for the name of the ship (a string) - A member variable for the year that the ship was built (a string) - A contsructor and appropriate accessors and mutators - A virtual print function that displays the ship's name and the year it was built (nobody seems to get this part...

Assume the Student and Employee classes each extend the Person class. The Student class overrides the getMoney method in the Person class. Consider the following code: Person p1, p2, p3; int m1, m2, m3; p1 = new Person(); m1 = p1.getMoney(); // assignment 1...
// Inheriting member functions // Please Make all changes as noted below: // 1) Make sayHello virtual function (hint this will be done in Person class // 2) Change main to create two Person pointer variables // 3) Set each pointer to one of the two objects already instantiated below // 4) Use the pointer variable to invoke the two sayHello() methods #include <iostream > #include <string > using namespace std ; class Person { protected : string name; int...
