In C++ The base class Pet has private 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

Define the class RectangularCube in C++. A RectangularCube has three sides length(L), width (W), and Height (h), define the sides as private data fields. Include a no-argument constructor that sets all three sides to 1. The class must also have a constructor that receive parameters to initialize sides of the RectangularCube. Include get and set functions for all three data fields. Finally define the functions volume () and surfaceArea () in the class RectangularCube that use the formulas given below to calculate and return the volume and the surface area of the RectangularCube. Give the UML diagram of the class, you may use the MSOffice/Visio to create the UML class diagram (best to download and use Visual paradigm tool, or any other free UML tool). Implement the class using separate files for definition and implementation, use inclusion guard to avoid duplicate code. Make sure to include at least one inline function implementation. Do not Implement the volume () and the SurfaceArea…

Redo Programming Exercise 3 by overloading the operators as nonmembers of the class boxType. Write a test program that tests various operations on the class boxType. Reference: Chapter 11 defined the class boxType by extending the definition of the class rectangleType. In this exercise, derive the class boxType from the class rectangleType, defined in Exercise 1, add the functions to overload the operators +,–, *, ==, !=, <=, <, >=, >, and pre- and post-increment and decrement operators as members of the class boxType. Also overload the operators << and >>. Overload the relational operators by considering the volume of the boxes. For example, two boxes are the same if they have the same volume. Write the definitions of the functions of the class boxType as defined above and then write a test program that tests various operations on the class.
