    // A class circle
    // The class will contain a member variable radius
    // The class will have a constructor method, which will accept a parameter radius
    // The class will have two methods: 
    // To get a area of the circle
    // To get circumference of the circle 
    // Now instantiate a circle object, passing radius of the circle 5. Call the methods (member functions to get area and circumference)
    // Instantiate another object, passing radius 10 and calculate the area and circumference
