Animal Lab
The objective of this assignment is to give you some practice using inheritance, virtual functions, and polymorphism.
Instructions:
Create a base class called Animal. All animals have a name (i.e. “Fido,” “Thumper,” “Princess,” “Nemo,” etc.) and an age. Provide a default constructor that initializes the age to zero and outputs the message “Invoking the default Animal constructor” and another constructor that allows the name and age to be set by the client. This other constructor should also output the message “Invoking the 2-argument Animal constructor.” Also construct a destructor for this class that outputs the message “Invoking the default Animal destructor.” Your Animal class should have a function called Move that cannot be implemented. That is, it should be declared as a purely virtual function. Your class should also have Get and Set methods to allow the name and age to be accessed.
From the Animal class, derive Dog, Rabbit, Fish, and Snake classes. The derived…
Object passing checklist1. Go over each member function and add the const keyword after their declaration ifthey do not modify any of the class' member variables.2. When accepting objects as parameters, prefer to pass them by reference. Add reference declarator (& before the identifier name of an object parameter.3. If the member function does not modify the parameter, make the parameter constantby using the const keyword.
apply the Object Passing Checklist. Modify food.h and volunteer.h to useobject references. Add const and & keywords in the appropriate places of the code.

- 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.

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.
