The variables should be labeled as X, Y , R for this circle class.

3a) Add some member variables to the Circle class 3b) Write an operatory> and operators for the Circle class so that you can do I/o with it. Look at the Rectangle class for an example of how to do this 3c) Write a distance_to() function for the Circle class, this should be pretty easy, as it's easy to use the Pythagorean theorem to find out how far away a point is, and to tell if that point is outside or inside the circle, and by now much by just subtracting the radius out of it
