ABOUT THE AUTHOR

DR. JACK PURDUM started his programming career on an IBM 360 mainframe

as a graduate student in the 1960s. In the mid-1970s, he became interested

in software development for microcomputers, and he founded his own soft￾ware development company (Ecosoft, Inc.) in 1977. The company’s main

product was a statistics package (Microstat) that he wanted to rewrite in a

new language called C. Lacking a suitable C compiler, Dr. Purdum’s company

developed its own MS-DOS-based C compiler and other programming tools.

He has been involved with language instruction ever since. Dr. Purdum has

authored 17 texts and numerous programming articles and has received several teaching awards. He

retired from Purdue University’s College of Technology and is currently involved with on-site train￾ing and embedded systems programming.

ACKNOWLEDGMENTS

NO BOOK IS WRITTEN without massive effort by others. Tom Dinse and the editorial staff at Wrox

have all made this a better book.

A large group of people also contributed to this book in a variety of different ways, providing every￾thing from encouragement to ideas for examples. First, thanks to my students who served as guinea

pigs for virtually everything used in this text. Others who contributed include Jerry and Barb Forro,

Bill Gromer, Joe Kack, Katie Mohr, John Purdum, and John Strack. A special vote of appreciation

to Jane Holcer for her unwavering support and encouragement throughout the process of writing

this book.
