C# C# Objects Methods Static vs Instance Methods

What xDiff =X-x mean ?

So when we say xDiff =X-x x is going to get the value that we are going to pass whenever we create a point on the Map . But what would be the value for X ?Is it the readonly value that we passed when we created the object map
Map map=new Map(8,5) ? Or It is something else that I am not getting?

Thanks

Hey Kosta,

The DistanceTo method is on the Point, The capital X and Y are properties of the Point class and initialized in the constructor when the class is created. The small x and y are the method arguments when the method is called. 

Point pointObj = new Point(4, 5);
pointObj.DistanceTo(3, 2);

//        X - x
//xDiff = 4 - 3

//        Y - y
// yDiff = 5 - 2

Hopefully this helps
