    {
        this.x = 0;
        this.y = 0;
    }
}

Coordinate point = Coordinate();
point.SetOrigin();

Console.WriteLine(point.x); //output: 0  
Console.WriteLine(point.y); //output: 0

Code Example 2

public struct Coords
{
    public Coords(double x, double y)
    {

        Y = y;
    }

    public double X { get; }
