                                              The container class libraries


          For more  Turbo C++ version 3.0 includes two complete container
 information about  class libraries: an enhanced version of the Object-
    templates, see  based library supplied with version 1.0, plus a brand-
  Chapter 13, "C++  new implementation based on templates. This chapter
       specifics."  describes both libraries. We assume that you are
                    familiar with the syntax and semantics of C++ and with
                    the basic concepts of object-oriented programming
                    (OOP). To understand the template-based version (called
                    BIDS, for Borland International Data Structures), you
                    should be acquainted with C++'s new template mechanism.

                    The chapter is divided into seven parts:

                    o A review of the difference between versions 1.0 and
                      3.0 of the class libraries
                    o An overview of the Object- and template-based
                      libraries
                    o A survey of the Object container classes, introducing
                      the basic concepts and terminology
                    o An overview of the BIDS library
                    o The CLASSLIB directory and how to use it
                    o Debugging tools
                    o An alphabetic reference guide to the Object container
                      library, listing each class and its members

                    The version 1.0 container library is an Object-based
                    implementation. Both container objects and the elements
                    stored in them are all ultimately derived from the
