Enumerations: The MSDN and my book shows the syntax of an enumeration requiring an ending

in the output of example 14-8 the last line displays:

The new array:
25 20 15 10 5 0

yet there's no corresponding code section for it in the code of example 14-8. I
assume that ouput should have been generated by an "intStack.Toarray()" command
followed by the proper "Console.WriteLine" statement iterated through the new array
to display its elements.

Example 15-3; (will be fixed in new edition per author)

that example and the related explanation doesn't make much sense and actually
confuses the reader more. a full explanation of it wouldn't fit in here, but there
are subtle errors in the code, like [Console.WriteLine( "
s2 = "Hello"; ");] which
first of all doesn't even appear in the representation of the output; it also
contains an extra semi-colon (guess which one it is?!) and s1 is the one set to
"Hello" on the next line, not s2. in the explanation you say [Now, returining to s1
and s2, ...] and then skip to [s3 = "Goodbye";] without even mentioning the
correlation between s1 and s2. on top of that. I believe that even after s1 and s3
are reassigned there still remains one instance of the original string referred to by
s1 (you said there weren't anymore) and that is s2 since it was created with the =
operator. Confused yet?
anyway, this whole example needs to be reviewed.

on page 392, btnCopy_Click was declared as:
private void btnCopy_Click(object sender, System.EventArgs e)
but now it's
protected void btnCopy_Click(object sender, System.EventArgs e)

One might get confused into thinking that they are 2 different event handlers.
