        MyStructure myS1 = new MyStructure();//OK
        myS1.i = 1;
        Console.WriteLine(" myS1.i={0}", myS1.i);

        //Another way of using structure
        MyStructure myS2 = new MyStructure(10);//OK
        Console.WriteLine(" myS2.i={0}", myS2.i);

        //Another way of using structure
        MyStructure myS3;
        myS3.i = 100;
        Console.WriteLine(" myS3.i={0}", myS3.i);

    }
}
