writte in c++  Write a Circle class that has the following member variables: • radius : a double • pi : a double initialized with the value 3.14159 The class should have the following member functions: • Default Constructor. A default constructor that sets radius to 0.0. • Constructor. Accepts the radius of the circle as an argument. • setRadius. A mutator function for the radius variable. • getRadius. An accessor function for the radius variable. • getArea. Returns the area of the circle, which is calculated as area = pi * radius * radius • getCircumference. Returns the circumference of the circle, which is calculated as circumference = 2 * pi * radius
C++ Friend function concepts Do not use operator overloading Create a class User with private member variables "id". In the class define a function increment_user_id() which will increment the id and return it as well. Create another method "void show_Id()" to show the id for a particular object. Create a constructor of User class where increment the Id by calling the increment_user_id() method for every new object . Finally create two objects of the class and print their corresponding id's on console.
