  int x, y;

     x = y = 0; 
  }

  public static bool operator |(TwoDimension op1, TwoDimension op2)

       ((op2.x != 0) || (op2.y != 0)) ) 
      return true;   
    else

    Console.WriteLine(x + ", " + y);   
  }

class MainClass {   
  public static void Main() {   
    TwoDimension a = new TwoDimension(5, 6);   
    TwoDimension b = new TwoDimension(10, 10);   
    TwoDimension c = new TwoDimension(0, 0);   
   
    Console.Write("Here is a: ");   
    a.show();   
    Console.Write("Here is b: ");   
    b.show();   
    Console.Write("Here is c: ");   
    c.show();   
    Console.WriteLine();   
 
    if(a | b) 
        Console.WriteLine("a | b is true."); 
    else 
        Console.WriteLine("a | b is false."); 
 
    if(a | c) 
        Console.WriteLine("a | c is true."); 
    else 
        Console.WriteLine("a | c is false."); 
  }   
}

Here is a: 5, 6
Here is b: 10, 10
Here is c: 0, 0

a | b is true.
a | c is true.
