The file below has the basic code for class Vehicles. Create this class using the procedure explained last time. Divide the code between Vehicle.h, Vehicle.cpp and driver.cpp as in the slides (Inheritance and Composition). Leave the subclasses Automobiles and pulled_vehicles alone for now. Complete the code for the class : 1- Adding a data member vName that will hold the vehicle name 2- defining and implementing two constuctors : default with these values 2 and "legs" for the data members and a parameterized constructor 3- defining and implementing the setters and getters. class Vehicles //base-class { // public members public: int No of_wheels; void set wheels (int w) No_of_wheels = W; } ; int main() Vehicle V1; return 0;
You are given a template to help you follow the required structure. There are 10 files for the base and derived classes with specification and implementation files You are also given a driver MagicalCreaturesMain.cpp that you will complete. So 11 files in all. MagicalCreatureHeader.h // given to you MagicalCreature.cpp // given to you ElfHeader.h // given to you Elf.cpp // you implement methods DragonHeader.h // given to you Dragon.cpp // you implement methods GoblinHeader.h // given to you Goblin.cpp // you implement methods GenieHeader.h // given to you Genie.cpp // you implement methods Specifications: Here are five UML Diagrams: One for the Base class and the others for the derived classes. Use these along with the given template to complete the design of the classes and create the application. The template contains comments and notation as to where you need to fill in the code;…
For this assignment you will be building on the Fraction class you began last week. All the requirements from that class are still in force. You'll be making five major changes to the class. Delete your set() function. Add two constructors, a default constructor (a constructor that takes no parameters) and a parameterized constructor (a constructor that takes parameters). The default constructor assigns the value 0 to the Fraction. In the parameterized constructor, the first parameter will represent the initial numerator of the Fraction, and the second parameter will represent the initial denominator of the Fraction.Since Fractions cannot have denominators of 0, the default constructor should assign 0 to the numerator and 1 to the denominator. Also, the parameterized constructor should check to make sure that the second parameter is not a 0 by using the statement "assert(denominatorParameter != 0);". To use the assert() function you'll also need to #include <cassert>.assert() is…

7. When a class contains objects of another class, the relationship is called a whole-part relationship or composition. The relationship created is also called a has-a relationship. Discuss some of the possible issues with composition, such as the long statement: Outputsales.getHighestPaidEmployee().getHireDate().getYear().
The total cost of a group of items at a grocery store is based on the sum of the individual product prices and the tax (which is 5.75%). Products that are considered “necessities” are not taxed, whereas products that are considered “luxuries” are. The Product class is abstract, and it has a method called getTotalPrice. Your task is to create two subclasses of Product: NecessaryProduct and LuxuryProduct and implement the getTotalPrice method in each of these classes appropriately. Then modify the driver program to instantiate four products (two necessary and two luxury) and store them in the product array, print out each item in the array, and display the total cost of the items. You should not make any changes at all to Product.java, and you should only add to ShoppingTripStartingCode.java. Do not change any code that is already present Example(Cheese and bread are necessities and soda and candy are luxuries)Cheese…
1. I Love Shapes by Codechum Admin Shapes are the best thing in the world! We see them everywhere, from triangular pizza pies to her perfectly shaped almond eyes ? For this program, you are tasked to implement the Shape class. This class should be an abstract class and should have the following properties: private String name private String color private boolean isFlat It should have a constructor with the following signature, public Shape(String name, String color, boolean isFlat), getter methods for all the properties, and a setter method for the color. Then implement two more abstract classes that inherit from this Shape class: TwoDShape and ThreeDShape. The TwoDShape will have the following additional details: Additional property: private int numberOfSides Additional methods: getter for the numberOfSides public abstract double getArea() public abstract double getPerimeter() Constructor with the following signature: public TwoDShape(String name, String color,…
please code in python Answer the following questions about this Dog class: [refer image for dog class] 1. Construct an instance of the Dog class whose name is Snickers and was born in2011 and assign that instance to a variable called myDog.2. Call the bark method so that myDog barks 3 times.3. Add a method to the Dog class called isPuppy that returns True if the dog is lessthan 1 year old.4. Add the __str__ method to the Dog class. It should return a string that includesthe dog’s name and age.

Consider a class "Fan" with two integer data members, "state" (0/1 i.e. on or off) and "speed". 1. Write a parameterized Constructor for this class. 2. Write a member function "changeState( )" which behaves similar to pressing a button i.e. it should change the state of the fan. If it is off (0), calling the function should turn it on (1) and vice versa.. Multi Line Text.
1. Create a class called Elevator that can be moved between floors in an N-storey building. Elevator uses a constructor to initialize the number of floors (N) in the building when the object is instantiated. Elevator also has a default constructor that creates a five- (5) storey building. The Elevator class has a termination condition that requires the elevator to be moved to the main (i.e., first) floor when the object is cleaned up. Write a finalize() method that satisfies this termination condition and verifies the condition by printing a message to the output, Elevator ending: elevator returned to the first floor. In main(), test at least five (5) possible scenarios that can occur when Elevator is used in a building with many floors (e.g., create, move from one floor to another, etc.). Hint: Termination occurs when the instance is set to null. You may wish to investigate “garbage collection” for this exercise.
