Create a base class called shape, this class to store two double type values (value1, value2) that could be used to compute the area of figures. Derive two specific classes called triangle and rectangle from the base shape. Add accessor and mutator function to the base class, to initialize and retrieve base class data members and another member function display_area() to compute and display area of figures.. Make display_area as pure virtual function and provide its definition in the derived class to suit their requirements. Using these three classes, design a program that will accept dimensions of a triangle or a rectangle interactively and display area. Run the above program with following requirements. Provide appropriate constructor in each class. Use constructor function to initialize the data members of base class.

Create a class named Line: (a) Define private data members p1 and p2 as pointer to Point objects (the one we had in lectures), slope and length as double variables. (b) Define setter and getter functions. (c) Define a null-constructor that initializes numeric variables with zero and allocate dynamic memory for points and initialize them to [0,0] as well. (d) Overload a constructor that allocates memory for points, initilize them with given arguments, and calculate the slope and length. (e) Implement destructor, copy constructor and copy assignment operator. (f) Create a function called ”parallel” that takes too Line objects, returns true when given lines are parallel and returns false otherwise. (g) Overload the less than (<) and greater than (>) and equality (==) operators (compare the length). (h) Write a functions that reads lines in the format provided in the lines.txt from the file (without any change) and stores them in a vector named Lines. (i) Sort the objects of Lines…

Double Bubble For this exercise you need to create a Bubble class and construct two instances of the Bubble object. You will then take the two Bubble objects and combine them to create a new, larger combined Bubble object. This will be done using functions that take in these Bubble objects as parameters. The Bubble class contains one data member, radius_, and the corresponding accessor and mutator methods for radius_, GetRadius and SetRadius. Create a member function called CalculateVolume that computes for the volume of a bubble (sphere). Use the value 3.1415 for PI. Your main function has some skeleton code that asks the user for the radius of two bubbles. You will use this to create the two Bubble objects. You will create a CombineBubbles function that receives two references (two Bubble objects) and returns a Bubble object. Combining bubbles simply means creating a new Bubble object whose radius is the sum of the two Bubble objects' radii. Take note that the CombineBubbles function…

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            //…
