assistant: I am wondering if there is a shareware/freeware serial I/O object type
perhaps derived from streambuf or ios?  Or is there a commercial one out
there?
I am interested in creating a door program using C++ objects and wondered if
I could get a serial i/o that was the same way.  So I could code:
serout << "Hello World!";
And it would send it to the serial port that I had previously set up.  Are
fossil drivers necessary?  Can someone tell me what they do in serial
communications?
Now for a different topic, multiple instances of the same program...like a
chat program, would the easiest way to transfer info be a file sharing
stem?
Thanks for the help,
Steve Westcot

All these OO[x]'s are just one way for Analysis Design Coding and Testting to
be used with objects.
    Note: SmallTalk and Java are pure object oriented languages because all
    code and data belong to an object. C++ is a hybrid language because
    it allows for code to exits as functions - like main().
    Anyways, the big deal with OO programming is that it is supposed to come
    closer to mimicing real life. It allows for objects to be highly cohesive
    and allow for loose coupling when interacting with other objects.
    Objects just pass messages back and for to each other. Like in real life,
    a Teacher gives assignments to a Student and the Student returns the
    assignment.
    Teacher Joe("computer science);
    Student computer_class[30];
    assg = Joe.GiveAssg();
    for (int i=0; i<30;i++) computer_class.GetAssg( assg );
    Modularity is the single component that allows for software to be
    intullectually managable. So, for an object, you don't have to
    remeber the "rules" for a procedure. The object is responsible for
    knowning the rules and being a self contained entity that can
    keep data to itself but allow access to information through intelligent
    methods (functions).

assistant: us
    In c++, static can have a few implied meanings.
    #1 a static int member in a class
       Say you have an array of students. Each student has a grade.
       Each student object also has a lowest limit for the grade and
       still be passing.
       class student {
         int grade;
         static int minimum_passing;
       }
       int student::minimum_passing = 50;
       In this case, all students share the ONE integer for minimum_passing
       grade. The value, also, may only be set once.
    #2 a static member function
       class something {
         static void do_something();
       };
       Normally to call do_something, you would have to have an object
       first.
          something a;
          a.do_something();
       A static function can be called without an object.
         something::do_something();
    #3 a static int within a kernel
       In an operating system, you may not want certain data structures
       to be allocated/deallocated on the fly. In this case static keeps
       the space for a data stuctures permenantly allocated to the program.
       In operating systems, like unix, many processes may share information
       and a static area withing the systems kernel can be used to share
       memory.

NEver tried. Most probably it will increment the error count. ;-)
???  You have as many ctors as you like. Just make 'em accept different
number or mix of type of the arguments. I like pascal's constructor keyword,
and ability to name the ctors freely, but in the practice you extremely
rarely need ctors with different behavior and the same arglist.  And even in
that case you can solve it.
Having multiple inheritance is good. Not easy to implement on the compiler
side, but comes really handy if fits in your modell.
The questionable things I count in C++ are inherited from C to keep
comatibility.

assistant: Hi, Cliff Rhodes!
On 09 Apr 97  16:11:04 you wrote to Balog Pal
Well. When you use a class library you time to time face the problem that
some of your derived classes need a parent change. Eg. you decide a
SortedCollection can be used instead of simple Colection, or you developed a
specialised Dialog with singigng Help button and want to refit old Dialog
derived stuff to use this instead.
It would not be a problem if you could sinply go to the class definition,
change the class after : and ready. A plenty of overridden functuins make
calls to the parent's similar function just to add some functionality before
or after that. And you must precisely replace all those calls to use the new
parent. In most cases you will not even get a warning from the compiler
missing one or two, but you'll likely have funny runtime bugs. ;)
The other painful thing is when you write the functions just mentioned. As
you must specify the parent name you must know it by heart or look up in the
header. (And if you use an app framework like MFC tha latter case is likely.
:)
The only solution for that problems I knew before was to use a #undef/#define
PARENT. But to use it you probably must take extreme care how you place your
implementation functions in the module, and how you include header files. In
some cases you may end up to use someone elese's parent and gain the same
problems mentioned above.
Using that scoped typedef really solves the problem, you just modify the
parent in two places located 1-2 lines to each other. And the scoping make
all your class functions use the correct parent in the implementation. :-)

Yes. But that's because MFC is a very poor OOP lib for that case. It's as you
stated before a very thin wrapper, nothing more. Anyone expecting true object
behavior will fall on face. (Like I did. :)  Fortunately it's quite well
armored with asserts so you can relatively easily figure out what happened. I
expected that controls and such elements will handle themselves, but they do
nothing but giva another form of calling the same old API functions. If
they're not on screen you simply get an assert termination or in release

You couldn't exploit it anyway. For any module defining class members you
will include the header defining the class structure. And xx will be there.
So the module will be able to call it.  (OTOH if you could force static,
you'd get an error at link time.)
And relating to member functions the `static' keyword has a new meaning (did
anyone count how much different things it does?).  A member function with
static attribute will not recieve a this member, so it can be called by its
own, not relating to an instance.
Or if it's virtual you can simply call it through the VMT. :)
That's not a good parabola. But let's see it closer. Unix is said to be safe.
You have a root account, protected with a password. So you say your files
belonging to root are safe from reading by others. The 700 privilege grants
that.
But if I can boot another opsystem on that machine (or remove the HD and
place in another machine) I can read your files though. a simple disk editor
will do the task.  Can unix be blamed for that? IMO no.  Nor can C++ be
blamed for your practices using asm to call the private members. You just
step out of its reach.
If you're really annoyed, you can write a simple program that removes PUBDEF
records from a .OBJ file, so getting the same behavior use of static would do
for you.

assistant: There are some differences, _but_ the differences are NOT relevant for
a project like this.  They are the same language.  It's the 'frills'
where they differ.  BC30 has better optimizations, utilities, etc.  BC
is for the professional programmer who needs the extras, and TC30 is for
the hobbiest who can get by without the extra utilities and better
optimizations.  But the language they implement is identical.  They have
the same parser, they have the same Borland extensions, etc.
asm
Pffftt..  The program is _designed_ for the medium memory model.  Not
for small, not for large, not for huge.  Regardless of the compiler, it
is _designed_ for the medium language.  Switching to a very different
compiler may require some changes to the code, but very unlikely to the
memory model. Changing from BC30 to a related, dumbed down version of
the compiler (ie: TC30) should require few to no changes.
As you gain some experience with computers and programming, you'll
realize what should and should not happen / be needed, etc.

They wrote:

Write your reply.

assistant: ROFL!  In a few years, when you've learned a bit more about programming,
differences in the code different compilers generate, how different
switches and optimizations can radically change the generated code,
programming for different platforms or even similar platforms but
different CPUs, etc., you'll realize just how incredibly funny that
statement is!! <VBG>
There is only so much you can do algorithmically in a HLL.  There comes
a point where it is very much up to the compiler as to how well / fast
the resulting executable runs.
For example, switching from a bubble sort to a quick sort might decrease
your run time from O(N^2) to O(N log N), but then after that, it's up to
the compiler whether it generates code that needs 10 seconds for 'x'
items, or 20 seconds for the same 'x' items.
Does the compiler generate inline ABS() and memcpy() functions or are
they so dumb they require calling a library routine.  When it transfers
memory, does it do it a byte at a time, or is it smart enough to take
advantage of things like 32 bit registers which can move 4 bytes at a
time.  Does the compiler automatically align things on word boundaries,
or does it generate code where a variable can be misaligned and require
more memory accesses?  Does the compiler allow generating better 486
level code, which is tuned to the way a 486 CPU operates, or does it
generate code for cruddy, slow 386s?
For many things, such as the few I mentioned above, you _have_to_depend_
on the compiler, because there is a good chance they are outside of your
control, and even if not, they might be dependant upon the user setting
or not setting some particular switch that may not be the default or
that may interact with some other switch.

It's not wrong.  You have told it that you only want one byte (exactly
8 bits up there!) when you put those colons in there.  Try adding
another field or make one of those wider.
Also, you have declared exactly the same thing for A and B.  When you
use a comma like that, it is just shorthand for what's in B.
That would completely defeat the purpose of bitfields.
In which case it would have been even more inappropriate to ignore your
request that the struct be a bitfield.  AH is hardly 96 bits wide.
Your compiler has several bugs, but this is not one of them.
