                               Notes:
       =========================================================

1.

The AP classes -- apvector, apmatrix, apstring, apstack and apqueue --
that are used in many programs in this book are available for downloading
from the College Board's AP Computer Science web page:

    http://www.collegeboard.org/ap/computer-science/html/classes.html

2.

If you are using an older C++ compiler that does not support
bool data type, uncomment (remove // ) on the #include "bool.h"
line in the apstring.h, apstack.h and apqueue.h files.
Otherwise comment out the following lines in the bool.h file
(add // at the beginning of each line):

typedef int bool;
const int false = 0;
const int true = 1;

3.

If your program uses the apstring class you need to set up a project
and add your program file and apstring.cpp to the project.

If your program uses the apvector, apmatrix, apstack or apqueue classes,
DO NOT add apvector.cpp, apmatrix.cpp, apstack.cpp or apqueue.cpp
to your project (these files serve as continuations of the
respective .h files).

For details on how to obtain and use the apvector, apmatrix, apstring,
apstack, and apqueue classes please see:
