In C++
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++ The class clockType was designed to implement the time of day in a program. Certain applications, in addition to hours, minutes, and seconds, might require you to store the time zone. Derive the class extClockType from the class clockType by adding a member variable to store the time zone called timeZone. Add the necessary member functions and constructors to make the class functional. Also, write the definitions of the member functions and the constructors. Finally, write a test program to test your class. Header file //clockType.h, the specification file for the class clockType #ifndef H_ClockType #define H_ClockType     class clockType  { public:     void setTime(int hours, int minutes, int seconds);        //Function to set the time.        //The time is set according to the parameters.         //Postcondition: hr = hours; min = minutes;         //               sec = seconds        //   The function checks whether the values of         //   hours, minutes, and seconds are…
