Some three decades have elapsed since Kathy Reed taught me what a computer was and how to program one, so I suppose this is really all her fault. In 1989, Donald French asked me to develop C++ training materials for the Institute for Advanced Professional Studies, so perhaps he should shoulder some blame. The students in my class at Stratus Computer the week of June 3, 1991, were not the first to suggest I write a book summarizing the pearls of alleged wisdom that tumble forth when I teach, but they were the ones who finally convinced me to do it, so they bear some of the responsibility. I'm grateful to them <NOBR>all.<SCRIPT>create_link(2);</SCRIPT>

Many of the Items and examples in this book have no particular source, at least not one I can remember. Instead, they grew out of a combination of my own experiences using and teaching C++, those of my colleagues, and opinions expressed by contributors to the Usenet C++ newsgroups. Many examples that are now standard in the C++ teaching community — notably strings — can be traced back to the initial edition of Bjarne Stroustrup's <NOBR><FONT COLOR="#FF0000" SIZE="-2"><B>°</B></FONT><A HREF="http://www.awl.com/cseng/cgi-bin/cdquery.pl?name=cpl" onMouseOver="self.status='The C++ Programming Language Home Page'; return true" onMouseOut="self.status = self.defaultStatus" TARGET="_top"><I>The</NOBR> C++ Programming Language</I></A> (Addison-Wesley, 1986). Several of the Items found here (e.g., <A HREF="./EI17_FR.HTM#2264" TARGET="_top">Item 17</A>) can also be found in that seminal <NOBR>work.<SCRIPT>create_link(3);</SCRIPT>

Many readers of the first edition sent suggestions I was unable to incorporate in that version of the book, but that I've adopted in one form or another for this new edition. Others took advantage of Usenet C++ newsgroups to post insightful remarks about the material in the book. I'm grateful to each of the following individuals, and I've noted where I took advantage of their ideas: Mike Kaelbling and Julio Kuplinsky (Introduction); a person my notes identify only as "a guy at Claris"<A HREF="#474"><sup>2</sup></A> (<A HREF="EI5_FR.HTM#1869" TARGET="_top">Item 5</A>); Joel Regen and Chris Treichel (<A HREF="EI7_FR.HTM#1894" TARGET="_top">Item 7</A>); Tom Cargill, Larry Gajdos, Doug Morgan, and Uwe Steinmüller (<A HREF="EI10_FR.HTM#1986" TARGET="_top">Item 10</A>); Roger Scott and Steve Burkett (<A HREF="./EI12_FR.HTM#2071" TARGET="_top">Item 12</A>); David Papurt (<A HREF="./EI13_FR.HTM#2117" TARGET="_top">Item 13</A>); Alexander Gootman (<A HREF="./EI14_FR.HTM#223029" TARGET="_top">Item 14</A>); David Bern (<A HREF="./EI16_FR.HTM#2225" TARGET="_top">Item 16</A>); Tom Cargill, Tom Chappell, Dan Fran<A NAME="pxix"></A>klin, and Jerry Liebelson (<A HREF="./EI17_FR.HTM#2264" TARGET="_top">Item 17</A>); John "Eljay" Love-Jensen (<A HREF="./EI19_FR.HTM#5887" TARGET="_top">Item 19</A>); Eric Nagler (<A HREF="./EI22_FR.HTM#6133" TARGET="_top">Item 22</A>); Roger Eastman, Doug Moore, and Aaron Naiman (<A HREF="./EI23_FR.HTM#6210" TARGET="_top">Item 23</A>); Dat Thuc Nguyen (<A HREF="./EI25_FR.HTM#6292" TARGET="_top">Item 25</A>); Tony Hansen, Natraj Kini, and Roger Scott (<A HREF="./EI33_FR.HTM#6729" TARGET="_top">Item 33</A>); John Harrington, Read Fleming, and Dave Smallberg (<A HREF="./EI34_FR.HTM#6793" TARGET="_top">Item 34</A>); Johan Bengtsson (<A HREF="./EI36_FR.HTM#7007" TARGET="_top">Item 36</A>); Rene Rodoni (<A HREF="./EI39_FR.HTM#7269" TARGET="_top">Item 39</A>); Paul Blankenbaker and Mark Somer (<A HREF="./EI40_FR.HTM#7424" TARGET="_top">Item 40</A>); Tom Cargill and John Lakos (<A HREF="./EI41_FR.HTM#7611" TARGET="_top">Item 41</A>); Frieder Knauss and Roger Scott (<A HREF="./EI42_FR.HTM#21052" TARGET="_top">Item 42</A>); David Braunegg, Steve Clamage, and Dawn Koffman (<A HREF="./EI45_FR.HTM#8160" TARGET="_top">Item 45</A>); Tom Cargill (<A HREF="./EI46_FR.HTM#195225" TARGET="_top">Item 46</A>); Wesley Munsil (<A HREF="./EI47_FR.HTM#8299" TARGET="_top">Item 47</A>); Randy Mangoba (most class definitions); and John "Eljay" Love-Jensen (many places where I use <CODE>type double</CODE>).<SCRIPT>create_link(5);</SCRIPT>
