6,377 PointsWhy use Point p = x; in the video?
Why use Point p = x; in below code? What is the purpose?
using System;
namespace TreehouseDefense
{
class Game
{
public static void Main()
{
Map map = new Map(8, 5);
Point x = new MapLocation(4, 2);
Point p = x;
Console.WriteLine(x.DistanceTo(5, 5));
Console.WriteLine(x is MapLocation);
Console.WriteLine(x is Point);
Point point = new Point(0, 0);
Console.WriteLine(point is MapLocation);
Console.ReadLine();
}
}
}

231,198 PointsThat line was simply for demonstration purposes.
When that line was added, on the line above it x was not a Point but a MapLocation. The "Point p = x;
" line was added to show that a MapLocation could be assigned to a Point.
After the demonstration, x was changed to be a Point on the line above (as shown in your code here), but the assignment of p was never removed.
