Part a) Create a base class called shape. Use this class to store two double type values that could be used to compute the area of figures. Derive two specific classes called triangle and rectangle from the base shape. Add to the base class, a member function get_data() to initialize base class data members and another member function display_area() to compute and display the area of figures. Make display_area() as a virtual function and redefine this function in the derived classes to suit their requirements. Using these three classes, design a program that will accept dimensions of a triangle or a rectangle interactively, and display the area.

Q1: Create two classes named Mammals and SeaAnimal. Create another class named Whale whichinherits both the above classes. Now, create a function in each of these classes which prints "I ammammal" in class Mammals, "I am a marine animal” in class Marine and "I belong to both thecategories: Mammals as well as Marine Animals" in class Whale. Now, create an object for each of theabove class in main function and try calling.1 - function of Mammals by the object of Mammal2 - function of SeaAnimal by the object of SeaAnimal3 - function of Whale by the object of Whale4 - function of each of its parent by the object of Whale

The base class Pet has protected data members petName, and petAge. The derived class Dog extends the Pet class and includes a private data member for dogBreed. Complete main() to: create a generic pet and print information using PrintInfo(). create a Dog pet, use PrintInfo() to print information, and add a statement to print the dog's breed using the GetBreed() function. Ex. If the input is: Dobby2Kreacher3German Schnauzer the output is: Pet Information: Name: Dobby Age: 2Pet Information: Name: Kreacher Age: 3 Breed: German Schnauzer #include <iostream>#include<string>#include "Dog.h" using namespace std; int main() { string petName, dogName, dogBreed; int petAge, dogAge; Pet myPet; Dog myDog; getline(cin, petName); cin >> petAge; cin.ignore(); getline(cin, dogName); cin >> dogAge; cin.ignore(); getline(cin, dogBreed); // TODO: Create generic pet (using petName, petAge) and then call PrintInfo //…
Rectangle Class Observe the Rectangle class in rectangle.h, and you'll see it has two member variables: length_ and width_. These member variables can be modified with the "Setter functions" SetLength and SetWidth (aka mutator functions) and can be retrieved with the "getter functions" GetLength and GetWidth (aka accessor functions). You will be implementing two member functions of the Rectangle class: Area, and Perimeter. Notice that if a function belongs to a class, when we define the function outside of the class, we indicate that it is a member function of a class using the :: operator. For example, because Area() belongs to the Rectangle class, when we define the function in rectangle.cc, it is written as: int Rectangle::Area() { ... } After implementing these two member functions, you will implement a function, LargestRectangleByArea that compares two input Rectangle objects and returns which of the two is larger, based on its area. Implement the member function Area that…

Create a class called Student with four (4) private member variables, name (string), quiz, midterm, final (all double type); Include all necessary member functions for this class (at least 1 constructor and 1 default constructor, 1 get function, and 1 grading function – see #5); Declare three (3) objects of Student type (individual or array); Read from the keyboard three (3) sets of values of name, quiz, midterm, final and assign them to each object; Using the object’s member function to calculate the grade for each student (grade = quiz * 0.2 + midterm * 0.4 + final * 0.4) Display on the screen only the name of each student and the grade.
10.25 LAB: Book information (overriding member methods) Given the base class Book, define a derived class called Encyclopedia. Within the derived Encyclopedia class, define a print_info() method that overrides the Book class' print_info() method by printing not only the title, author, publisher, and publication date, but also the edition and number of volumes. Ex: If the input is: The Hobbit J. R. R. Tolkien George Allen & Unwin 21 September 1937 The Illustrated Encyclopedia of the Universe James W. Guthrie Watson-Guptill 2001 2nd 1 the output is: Book Information: Book Title: The Hobbit Author: J. R. R. Tolkien Publisher: George Allen & Unwin Publication Date: 21 September 1937 Book Information: Book Title: The Illustrated Encyclopedia of the Universe Author: James W.

C++ : Define a new class Fighter that inherits from the Spaceship class below. - Add a private member variable: int firePower; - Create a default constructor which initializes firePower to 10 and initializes name to "X-wing" - Create a member function in Fighter void warp(). This function should increase position by 10, and decrease health by 5. - Redefine function wasHit(). Instead of decrementing health by 5, decrement it by 2. class Spaceship { protected: string name; int health; int position; public: Spaceship() { name = ""; health = 100; position = 0; } void moveLeft() { position--; } void moveRight() { position++; } void wasHit() { health -= 5; } };

7. PersonData and CustomerData classesDesign a class named PersonData with the following member variables:lastNamefirstNameaddresscitystatezipphoneWrite the appropriate accessor and mutator functions for these member variables. Next, design a class named CustomerData, which is derived from the PersonData class. The CustomerData class should have the following member variables:customerNumbermailingListThe customerNumber variable will be used to hold a unique integer for each customer. The mailingList variable should be a bool. It will be set to true if the customer wishes to be on a mailing list, or false if the customer does not wish to be on a mail- ing list. Write appropriate accessor and mutator functions for these member variables. Demonstrate an object of the CustomerData class in a simple program.
Write code to create a class named as ‘Employee’ with attributes i.e. ID, Name, Designation, Qualification, Salary, Taken-Leaves, Allowed-Leaves and the functions applyLeave(). This function will take number of leaves as an input and check Allowed-Leaves to see whether the employee can take leaves or not. If he can take, deduct these leaves from Allowed-Leaves and add in Taken-Leaves. Otherwise show message ‘you cannot take leave’. Create another class ‘Intern’ and inherit ‘Employee’ as super class.
