Hi, I have seen a lot of talk about dynamic typing in objective-c.

Let's take the following code as an example: ASPX: <form id="form1" runat="server"> <div> <asp:Panel runat="server" ID="controls" /> </div> </form> CS: protected void Page_Init(object sender, EventArgs e) { B...

I know that each object - when created - will be given space in the HEAP for member variables, and I think that all the code for every function that belongs to that type of object exists in the code segment in memory - permanently. Is that...
