RP>   What is the difference between C and C++
   That would take a while to explain!
   In short, though, C++ has a few new keywords, such as new,
   delete, and class. It supports function and operator
   overloading. It supports data object conversions. It
   supports the three principles of OOD, which are
   encapsulation, inheritance, and polymorphism. Encapsulation
   is keeping your data objects separate from the environment
   in which they are created. All the code used to manipulate
   those objects are part of the data object itself. Creating a
   String automatically gives you the code to manipulate that
   string, but you cannot actually manipulate that string,
   EXCEPT via that code. It is safe from mishandling because it
   is encapsulated within the class within which resides its
   code object. You may derive a class from any given class,
   and it will inherit all or part of the data and code objects
   which belong to that class, unless you override those data
   or code objects in your derived class, which is known as
   polymorphism. You get everything if you want it, but you
   don't have to take anything you don't want.
   Typical C code will contain many calls to library functions
   to carry out the application objectives. C++ code will
   seldom access library functions openly. All of that is done
   within the support code for the data objects. A class which
   has been constructed to handle a certain type of data will
   handle it just as well in any application into which it is
   included, without the programmer who includes it having the
   ability to mess it up, whereas users of C libraries will
   invariably, ( at least in my case :), find some way of
   messing up common usage of C functions. If you want to use
   C++, you should start by learning how classes are defined,
   what they are, and how they work. They are the heart of OOP.
