C++ please

Design and implement a class named Time. The class should store the tim in three integers- hour, minute, second. Implement two constructors for the class-a default constructor and a fully-parameterized constructor. Implement a member function that increments the minute by 1 and recognizes when the minute goes into a new hour by updating the hour member variable accordingly. Implement a member function that displays the time in the hh:mm::ss format. Don't worry if you end up with a time formatted like this: 1:1:1. Implement getters and setters for each member variable. Write code to test each feature of the class. Design and implement an Employee class. It will have the following member variables: name, idNumber(int), department, and position. It will only have two constructors, a default constructor and a fully-parameterized constructor. Create getters and setters for each member variable. Create three Employee objects and display the data for each object on the screen using the getter member functions. Design and implement a Circle class that has the following member variables: radius (double) and pi(constant initialized to 3.14159). Create a default constructor that sets the radius to 0.0 Create a fully parameterized constructor. Write getters and setters for the radius member variable. Write a member function, getArea(), that returns the area of the circle. The area is found by the following formula: pi radius radius. Write code to test the class definition 1. 2. 3
