2 Sams Teach Yourself C++ in 21 Days

This book uses various typefaces to help you distinguish C++ code from regular English.

Actual C++ code is typeset in a special monospacefont. Placeholders—words or charac-

ters temporarily used to represent the real words or characters you would type in code—

are typeset in italic monospace. New or important terms are typeset in italic.

In the listings in this book, each real code line is numbered. If you see an unnumbered

line in a listing, you’ll know that the unnumbered line is really a continuation of the pre-

ceding numbered code line (some code lines are too long for the width of the book). In

this case, you should type the two lines as one; do not divide them.
