- Explain why memberwise assignment can cause problems with a class that contains a pointer member.arrow_forwardRectangle 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…arrow_forward(RationalNumber Class) Create a class RationalNumber (fractions) with these capabilities:a) Create a constructor that prevents a 0 denominator in a fraction, reduces or simplifiesfractions that are not in reduced form and avoids negative denominators.b) Overload the addition, subtraction, multiplication and division operators for this class.c) Overload the relational and equality operators for this classarrow_forward
- Develop class Polynomial . The internal representation of a Polynomial is an array of terms. Each term contains a coefficient and an exponent—e.g., the term 2x4has the coefficient 2 and the exponent 4. Develop a complete class containing proper constructor and destructor functions as well as set and get functions. The class should also provide the following overloaded operator capabilities: "Overload the subtraction operator ( - ) to subtract two Polynomial s."arrow_forwardTo overload a function in a child class, inherited from its base class, the function must be a which one: virtual function overridden function binary function inherited functionarrow_forwardDouble 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…arrow_forward
- 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 //…arrow_forwardEach member-function definition outside its corresponding class template definitionmust begin with template and the same template parameters as its class template T/Farrow_forward1) This type of polymorphism is achieved by overriding functions Options: a) Run-time polymorphism b) Compile-time polymorphism c) Inheritance time polymorphism 2) C++ has the ability to provide operators with a special meaning for a data type Options: a) This capability is known as operator overloading b) This ability is known as heredity c) This ability is known as polymorphismarrow_forward
- . Write a class definition that creates a class called leverage with one private data member, crowbar, of type int and one public function whose declaration is void pry(). Write a member function called getcrow(). This function should return the value of the crowbar data. Assume the function is defined within the class definition. Opp Javaarrow_forwardOne use of the this pointer is to access a data member when there is a local variable with the same name. For example, if a member function has a local variable x and a data member x, then you can refer to the data member as this->x. Use this fact to complete the constructor implementation of this Point class: class Point { public: Point(int x, int y); int get_x() const; int get_y() const; private: int x; int y; }; Not all lines are useful.arrow_forwardUSE TEMPLATE PROVIDED AT END OF QUESTION WHILE MAKING SOLUTION ----------------------------------- Write a program to implement Hierarchical Inheritance A class called Bill has the following protected data member variables Datatype Variable name int billNumber string name Include the following member function in the Bill class Member function Description void generateBill() This function is used to display the bill number and customer name.
