Confusion about object

The value is not assigned in the second line to illustrate that it's a different object to the one created in the third line. Consequently the third line prints 10 which is the default value of x.

If you do assign the object in the second line to a variable and then use that, you will get different values:

using System;

class demo

{

int x=10;

public demo()

{

}

static void Main()

{

Console.WriteLine(new demo().x); //1st line

demo d1 = new demo();

d1.x = 20; //2nd line

Console.WriteLine(d1.x);

demo d2=new demo();

d2.x = 30; //3rd line

Console.WriteLine(d2.x);

Console.ReadLine();

}

The output is now:
