Example 5-5. Using an enumeration

enum Temperatures
{
WickedCold = 0,
FreezingPoint = 32,
LightJacketWeather = 60,
SwimmingWeather = 72,
BoilingPoint = 212,
}

should read ---

enum Temperatures
{
WickedCold = 0,
FreezingPoint = 32,
LightJacketWeather = 60,
SwimmingWeather = 72,
BoilingPoint = 212
}

There should not be comma after the last item in the list, 212.

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.

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

The second code fragment under Controlling Access

The copyright page of my book shows:

Printing History:
September 2002: First Edition

This section is mentioned under "Changes made in the 6/06 reprint" section of your

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.

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?

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."
