Errata and Source Code
Updated January 24, 2009

Errata/Gotchas list

Every author endeavors for perfection. My apologies for the typos that have slipped through. We'll do our best to have these corrected for the next printing. What's a 'gotcha'?

It's not an errata--but it is something that, for whatever reason, people are missing.

Gotcha #1--the Command Prompt (Page 44)

A number of people reports problems when they open up a command window that they are not seeing the same thing displayed in the book. That's perfectly fine.

What you see, in the title bar of the Command Window, is the 'Current folder' or 'Current directory' that the Command Window places you in. Regardless of what it happens to be, you can still 'navigate' to the correct folder by using the CD command illustrated on page 44, which a bunch of people are missing. Using the CD command, you can get to the location of your C++ Source file--no matter where it is. And, provided you have properly installed your compiler, you can then execute your program from anywhere.

General problem with cin.getline(response,256);

I'm receiving reports that this line of code 

cin.getline(response,256);

is failing to permit the user to enter a response when used with certain compilers such as

• Bloodshed

If so, replace it with this one

cin >> response;

and you'll be OK.

Chapter 1

• Page 11, 4th paragraph: "...will cause him to think of something else he wants to the program to do." Extra "to" in there.

Chapter 3

• Page 109, under the Increment Operator. "In other programming language, this code..." should be "In other programming languages, this code.."
• Page 127, middle of the page. "...and your right-hand expression is just the number 99." should be "...and your right-hand expression is just the number 88."

Chapter 4

• Page 151, last line of code in Step 1. This should contain a 'return 0' statement.
• Page 172, code in Exercise 4-7. This line

        const float MATH_MIDTERM_PERCENTAGE =.5F;

        should be 

        const float MATH_MIDTERM_PERCENTAGE =.50;

Chapter 7

• Page 293. If you attempt to compile Example7_1.cpp, be sure to code the Banner.cpp program on Page 289.
• Page 294. "I though the compile failed?" should be "I thought the compile failed?"
• Page 296, 8 lines from the bottom. "So can we can retrieve the value" should be "So can we retrieve the value"

Chapter 9

• Page 395. "Finally, we also have the public Calculate() Method, which outputs the employee's information to the C++ console " This should read "Finally, we also have the public Display() Method, which outputs the employee's information to the C++ console 
• Page 400, 5th line of code. The SalariedEmployee class erroneously is deriving from EmployeeBase. EmployeeBase isn't introduced until Page 411. The code should read...

        class SalariedEmployee: public Employee

• Page 400. The code in SalariedEmployee should not yet have a SalariedEmployee Constructor. Please remove it.
• Page 408. Dave, in his discussion, points out that the Constructor for Employee is executing. Because the book erroneously included a SalariedEmployee Constructor on Page 400, you may have noticed that run ALSO. Notice that we then added the SalariedEmployeeConstructor on Page 408.

Chapter 10

• Page 448. This section is confusing because I imply that the number contained within brackets is the 'upper floor' of the array. The number contained within brackets is the total number of elements (size) of the array.
• Page 448. To be consistent with the followon discussion, this line of code...

int grades[6];

should read

int grades[5]

• Page 448. "...was actually a string array containing 257 elements..." should read "...was actually a string array containing 256 elements..."
• Page 482, Discussion. Last sentence of the first paragraph reads "We declared grades as an array of the double data type..." We actually declared it as a float data type.

Chapter 11

• Page 510, last 3 lines. I say you can reference an array name to display the address of an array, but then I use the pointer name in the example. Change the code to read like this…

Cout << “The value of pGrades is “ << Grades << endl;
