Our aim in writing this book was to provide an extensive set of C++
programs for solving basic numerical problems with verification of the
results. This C++ Toolbox for Verified Computing I is the C++ edition of
the Numerical Toolbox for Verified Computing l. The programs of the
original edition were written in PASCAL-XSC, a PASCAL eXtension for
Scientific Computation. Since we published the first edition we have
received many requests from readers and users of our tools for a version
in C++. We take the view that C++ is growing in importance in the field
of numeri- cal computing. C++ includes C, but as a typed language and
due to its modern concepts, it is superior to C. To obtain the degree of
efficiency that PASCAL-XSC provides, we used the C-XSC library. C-XSC is
a C++ class library for eXtended Scientific Computing. C++ and the C-XSC
library are an adequate alternative to special XSC-Ianguages such as
PASCAL-XSC or ACRITH-XSC. A shareware version of the C-XSC library and
the sources of the toolbox programs are freely available via anonymous
ftp or can be ordered against reimbursement of expenses. The programs of
this book do not require a great deal of insight into the features of
C++. Particularly, object oriented programming techniques are not
required.
