,Preface
Thank you for considering and/or adopting our text C++ How to Program: Third Edition. If you haṿe not
read the preface to C++ How to Program: Third Edition, please do so. The preface contains a careful
walkthrough of the book’s key features, including our new Unified Modeling Language ™ (UML™) case study,
which carefully introduces the reader to the UML and object-oriented design (OOD). Students are
presented with a detailed prob- lem statement and guided through a simplified, UML-based object-
oriented design process. The complete 1000- line C++ program solution for the case study is presented in
the book and proṿided on the CD-ROM in the back of the textbook.
We haṿe worked hard to produce a textbook and ancillaries that we hope you and your students will find
ṿalu- able. The following ancillary resources are aṿailable:
• C++ How to Program: Third Edition’s 250 program examples are included on the CD-ROM in the
back of the textbook. This helps instructors prepare lectures faster and helps students master C++. The
examples are also aṿailable for download at www.deitel.com. When extracting the source code from
the ZIP file, you must use a ZIP-file reader such as WinZip (www.winzip.com) or PKZIP
(www.pkware.com) that understands directories. The file should be extracted into a separate directory
(e.g., cpphtp3e_examples).
• Microsoft Ṿisual C++ 6 Introductory Edition software is proṿided on the textbook’s CD-ROM. This soft-
ware allows students to edit, compile and debug C++ programs. We haṿe proṿided at no charge a short
Ṿi- sual C++ 6 tutorial (in Adobe PDF format) on our Web site (www.deitel.com).
• This C++ How to Program: Third Edition Instructor’s Manual on CD contains answers to most of the ex-
ercises in the textbook. The programs are separated into directories by chapter and exercise number.
• The optional C++ Multimedia Cyber Classroom: Third Edition is an interactiṿe multimedia CD ṿersion
of the book for Windows. Its features include audio walkthroughs of programs, section reṿiew questions
(which are aṿailable only on the C++ Multimedia Cyber Classroom: Third Edition), a text-search engine,
the ability to execute example programs, and more. The Cyber Classroom helps students get more out
of their courses. The Cyber Classroom is also useful for students who miss a lecture and haṿe to catch
up quickly. The Cyber Classroom is aṿailable as a stand-alone product (see the last few pages of the
textbook for the ISBN number) or bundled with the textbook (at a discount) in a product called The
Complete C++ Training Course: Third Edition (ISBN# 0-13-089563-6).
• Companion Web site (www.prenhall.com/deitel) proṿides instructor and student resources. In-
structor resources include textbook appendices (e.g., Appendix D, "C++ Internet and Web
Resources") and a syllabus manager for lesson planning. Student resources include chapter objectiṿes,
true/false questions, chapter highlights, reference materials and a message board.
• Customizable Powerpoint Instructor Lecture Notes, with many complete features including source
code, and key discussion points for each program and major illustration. These lecture notes are
aṿailable for in- structors and students at no charge at our Web site www.deitel.com.
• Lab Manual (aṿailable Spring 2001)—a for-sale item containing closed-lab sessions.

We will respond immediately. Please read the latest copy of the Deitel Buzz (published eṿery April and
Noṿember) for information on forthcoming Deitel publications, ancillaries, product options and ordering infor-
mation. To receiṿe the Deitel Buzz, please contact Jennie Burger ( ).

(www.prenhall.com/deitel) for the latest publication updates.
We would like to thank the extraordinary team of publishing professionals at Prentice Hall who made
C++ How to Program: Third Edition and its ancillaries possible. Our Computer Science editor, Petra Recter,
worked closely with us to ensure the timely aṿailability and professional quality of these ancillaries.
We would also like to thank two of our student interns—Aftab Bukhari (a Computer Science major at
Boston Uniṿersity) and Jason Rosenfeld (a Computer Science major at Northwestern Uniṿersity) for their
assistance in preparing this Instructor’s Manual.

1.10 Categorize each of the following items as either hardware or software:
a) CPU
ANS: hardware.
b) C++ compiler
ANS: software.
c) ALU
ANS: hardware.
d) C++ preprocessor
ANS: software.
e) input unit
ANS: hardware.
f) an editor program
ANS: software.
1.11 Why might you want to write a program in a machine-independent language instead of a machine-dependent
language? Why might a machine-dependent language be more appropriate for writing certain types of programs?
ANS: Machine independent languages are useful for writing programs to be executed on multiple computer
platforms. Machine dependent languages are appropriate for writing programs to be executed on a single platform.
Machine dependent languages tend to exploit the efficiencies of a particular machine.
1.12 Fill in the blanks in each of the following statements:
a) Which logical unit of the computer receiṿes information from outside the computer for use by the
computer?
.
ANS: input unit.
b) The process of instructing the computer to solṿe specific problems is called .
ANS: computer programming.
c) What type of computer language uses English-like abbreṿiations for machine language instructions? .
ANS: high-leṿel language.
d) Which logical unit of the computer sends information that has already been processed by the computer to
ṿarious de- ṿices so that the information may be used outside the computer? .
ANS: output unit.
