C++ OOP 1.    Write a class declaration named Circle with a private member variable named radius. Write set and get functions to access the radius variable, and a function named getArea that returns the area of the circle. The area is calculated as 3.14159 * radius * radius. Add a default constructor to the Circle class, the constructor should initialize the radius member to 0.

C++ coding project just need some help getting the code thank you!

C++ Dont include new files. READ ME PetsBreed ClassCreate a Breed class with the following: Member VariablesCreate the following private member variables, all of type std::string: species_breed_name_color_ConstructorsCreate a default constructor for Breed that sets its species_ to "Dog", breed_name_ to "Pug", and color_ to "Fawn".Create a non-default constructor that receives a std::string for species_, breed_name_, and color_; in that order. The values from the constructor should appropriately assign the member variables.Accessors and MutatorsCreate accessors and mutators for all member variables, following the naming conventions covered in class. e.g. for species_, name the accessor Species, and the mutator SetSpecies.

C++ please help me answer this question I will give you a good rating Thank you! Choose the correct answer to the question. Which of these is not a property of a class? Member variables and member functions may be public, protected, or private. A class may not use another class as the type for a member variable. The name of a member function for a class may be overloaded just like the name of an ordinary function. A function may have formal parameters whose types are classes. A function may return an object of a class. Choose the correct answer to the question.The copy constructor is executed... When one object is assigned to another object at its creation When objects are passed to a function using call by value When the function returns an object reference.b, c only a, b onlyAll of the above
