Preface

This is a document that is meant to be a supplement the text for the instructor.

There is a discussion of the ideas in each chapter, teaching

suggestions, and some supplementary ideas. There are solutions to many of the programming problems.

Some problems have several different

solutions that correspond to different paths through the book. There are 25 to 50 test questions with answers and discussion for each chapter. The

questions are of both short answer (multiple choice, true false, fill in the blank) type as well as read-the-code questions and short programming

problems.

I urge that explanations to the short answer questions be required of the student.

With regard to the content of this manual, it should be noted that C++ leaves many options on how to do any problem, and any book will

necessarily choose a subset to present. Our author has made such a set of choices. I have also made what I hope is a complementary set of choices

for this

Instructor's resource Manual

. I am striving to produce a complementary document to the text, a document for the instructor, but I

necessarily will do some things differently. Please do not hold the student responsible for what I have put here. The reader of this document must

note that it is necessary to read the text, as that is what the student has to work with. In spite of our efforts at consistency of content and style,

there will be some variance between some of the presentation here and the presentation in the text.

The code has been compiled and tested with g++ (gcc 3.4.4), Visual Studio C++ .NET 2003, Visual Studio C++ .NET 2005, Visual Studio C++

Express .NET, and Visual Studio C++ 6.0 updated to service pack 6.

Users of Microsoft Visual Studio C++ 6.0 may experience the most

incompatibilities and should ensure that service pack 6 is downloaded and installed from the Microsoft website.

The text uses only mainstream

features of C++, consequently, most compilers will compile the code and produce output that does not differ significantly from the results

presented here. We have attempted to supply warnings where any of these compilers gives trouble.
