Exercise 5.3
Point setters

In the Point class on the accompanying slide we have shown how to program getter properties in the class Point. Extend the four properties with setters as well. The new version of this class will support mutable points.

Write a small client program that demonstrates the use of the setter properties.

Hint: Please be aware that the revised class should allow us to get and set the rectangular and polar coordinates (x, y, angle, radius) of a point independent of each other. You should first consider what it means to do so.
