577 Pointsquestion regarding the first overload example shown
public int DistanceTo(Point point) { return DistanceTo(point.X, point.Y); } In this example of overloading why do we have to specify return (point.X, point.Y); I tried running it written as return DistanceTo(point); and it doesn't work. I thought it would be implicit that a point object has an X and Y as set up in the fields. I understand that the new overload method allows for this type of call Console.WriteLine(point.DistanceTo(pointTwo)); just would not have thought to write the method this way if It had been presented in an objective. Thank you for your time.

231,268 PointsThe overloaded version that takes a single "Point" argument is calling the other version (the one that uses two coordinates) to compute the distance.
If you change the return to call "return DistanceTo(point)
" instead, that makes it call itself which would cause an infinite recursion loop.
