UNCONFIRMED  errors and comments from readers: 


(86)  example 5-9;
Party.Democrat is hard wired, yet output still states that a valid choice was not
made.


{107} Example 8-7, Static Fields
Example 8-7, Static Fields, lines 15 and 19.  The VS editor doesn't recongnize the
word "String" as the C# string keyword because of the capital "S".  Lines 15 and 19
should be changed to read "private string name;" and "public Cat(string name, int
weight)".

This problem doesn't seem to affect program compilation and execution; however,
prevent the VS editor from displaying the string keywords in a blue font color.
Keywords in a default editor configuration are shown in blue.


(150)  "public int Hour" Property;
set should be indented to be inline with get


{155}  Example 8-4 code Passing by reference ;
In the example code around line 25 he has posted

public void GetTime(int theHour, int theMinute, int theSecond)
        {
            theHour = Hour;
            theMinute = Minute;
            theSecond = Second;
        }


It should have

public void GetTime(ref int theHour, ref int theMinute, ref int theSecond)
        {
            theHour = Hour;
            theMinute = Minute;
            theSecond = Second;
         }

or the example code doesnt compile in visual C# express



{200}  The second code fragment under Controlling Access;
The copyright page of my book shows:

Printing History:
  September 2002:  First Edition
  February 2006:   Second Edition

And the bottom right hand corner says: [6/06]
-- -- --
This section is mentioned under "Changes made in the 6/06 reprint" section of your
web site.  This is what is shown on your page:

[start excerpt]
{200}  under Controlling Access;
MyOtherClass inherits myValue from MyClass thus the definition of MyOtherClass

public class MyOtherClass : MyClass
{
  Console.WriteLine("myInt: {0}", myInt);
}

NOW READS:

public class MyOtherClass : MyClass
{
  Console.WriteLine("myInt: {0}", myValue);
}

Furthermore, all subsequent appearances of myInt in the Controlling Access section
HAVE BEEN CHANGED to myValue
[end excerpt]

My book has the myValue changes but the class declaration reads:

public class MyClass : MyOtherClass
{
  Console.WriteLine("myInt: {0}", myValue);
}

The order of MyClass and MyOtherClass should be reversed since MyOtherClass derives
from MyClass.



{269, 270 and 271}  Example 17-3, Example 17-4 and Example 17-5;
In Examples 17-3, 17-4 and 17-5, the statement 'string s1 = "abcd"' is not used and
gives a compiler error.



(282)  Output for example 14-4;
The last line of the output appears to be a typo.

Output for 14-4:

0 5 10 15 20
100 101 102 103 104
empArray.Capacity:  8    <-------

Is this supposed to be empList.Capacity:  5?



(413)  3rd paragraph;
...causes the page to be sent to the browser...
should probably be:
...causes the page to be sent to the server...


{440}  Solution to Exercise 3-2;
myFloat is declared twice in the program.

float myFloat = 4.25f;
...
...
float myFloat = 25.267f;


(475)  Last line of the Solution to Question 13-7;
The last line should be:
as "ILoggedCompressible extends ICompressible."
instead of being:
as "ILoggb[edCompressible extends ICompressible."
