Write a class declaration for a class named Circle, which has the data member radius, a double, and member functions setRadius and getArea. Write the code for these as inline functions.
Rewrite the calculator program using a class called calculator.
Your program will keep asking the user if they want to perform more calculations or quit and will have a function displayMenu to display the different functions e.g .(1 - addition, 2- subtraction, 3- multiplication, 4- division)
Your program must have appropriate constructors and member functions to initialize, access, and manipulate the data members as well as :
A member function to perform the addition and return the result
A member function to perform the subtraction and return the result
A member function to perform the multiplication and return the result
A member function to perform the division and return the result
Define a Pet class that stores the pet’s name, age, and weight. Add appropriateconstructors, accessor functions, and mutator functions. Also define a functionnamed getLifespan that returns a string with the value “unknown lifespan.” Next, define a Dog class that is derived from Pet. The Dog class should have aprivate member variable named breed that stores the breed of the dog. Add mutator and accessor functions for the breed variable and appropriate constructors.Redefine the getLifespan function to return “Approximately 7 years” if the dog’sweight is over 100 pounds and “Approximately 13 years” if the dog’s weight isunder 100 pounds. Next, define a Rock class that is derived from Pet. Redefine the getLifespanfunction to return “Thousands of years.” Finally, write a test program that creates instances of pet rocks and pet dogs thatexercise the inherited and redefined functions.
