I need help.

Preliminary task:

A point in the x-y plane is represented by its x-coordinate and y-coordinate. Design a class, pointType, that can store and process a point in the x-y plane. You should then perform operations on the point, such as showing the point, setting the coordinates of the point, printing the coordinates of the point, returning the x-coordinate, and returning the y-coordinate.

Every circle has a center and a radius. Given the radius, we can determine the circles area and circumference. Given the center, we can determine its position in the x-y plane. The center of a circle is a point in the x-y plane. Design a class, circleType, that can store the radius and center of the circle. Because the center is a point in the x-y plane and you designed the class to capture the properties of a point, you must derive the class circleType from the class pointType. You should be able to perform the usual operations on a circle, such as setting the radius, printing the radius, calculating and printing the area and circumference, and carrying out the usual operations on the center.

pointType.h and circleType.h will be given where there are only function headers. Function bodies need to be defined in pointTypeImp.cpp and circleTypeImp.cpp and the main function will be in the mainLab2.cpp

Please test all the member functions such as getting, setting, and printing out the center and radius, and calculating and printing the area and circumference.
