          Something about: Borland c++
 First of all do not confuse Borland C++ with Turbo C++.
 Turbo C++ 3.0 for dos is a hobbyist/low budget package.
 Borland C++ is more of a professional package.  It costs
 about 4 times as much as Turbo C++.
 To answer you question, Turbo C++ 3.0 and Borland C++ 3.1
 were the last C++ packages to have the DOS IDE.  You can
 still purchase Turbo C++ 3.0, but you may have to look
 around for Borland 3.1.

user: You are replying to All about "UNIX's fork".

Write your reply.

assistant: Hello.
I hope I can ask this in here.
This involves running concurrent processes in UNIX using
fork().
Does anyone know how to pass variables from a parent process
to a child process?
e.g I have a variable producer. Then I create a child process.
char producer = 'A';
int pid = fork();                // now we have 2 processes
I want to increment producer to 'B' and pass it to the child.
The other way of doing this is creating a variable which is
shared in memory so that any process can access it.
I have no idea how to make shared memory variables either.
Any ideas.

Write your reply.

assistant: Well, I don't agree that the number of switch statements is any
 good indicator of code quality.  Some people like to use switch
 statements and some like to use lots of if/else ifs to do the
 same.  The only drawback I see to switches is how 'break' gets
 overloaded.
 Not at all!
 But there's one "traditional use" of switch that becomes a questionable
 practice if you want to do object oriented programming.  That's the case
 where you have some sort of object type member embedded within the
 object and  then perform different actions based on this type.
 One example would be an employee setup where there's a field which
 holds job type.  Let's further assume that you have cases where you
 do different things based on that job classification
 double CalculateBonus (const Employee& employee) {
   switch (emp.job_code) {
     case UPPER_MANAGEMENT:
       return stock_price * media_hype;
     case TECHNICAL_STAFF:
       if (employee.IsUseless() && employee.SucksUpToBoss())
         return BIG_BUCKS;
       else
         return CHUMP_CHANGE;
     case JANITORIAL_STAFF:
         return 0;
   }
 }
 When you are choosing different actions based on type, then you
 should give strong consideration to having having different types
 of objects to represent this rather than some sort of type
 field.  Then CalculateBonus() becomes a virtual function that
 needs no maintenance when new types of employees are created
 withing the system.

assistant: operator char*()

Normally I recommend avoiding these types of conversions.  However, in a
RomanNumeral class, they actually make sense.  They really ARE two different
representations of the same thing!
Not in this case.  You have str pointing to valid memory, and then you point
it at other valid memory, without deallocating the first valid memory.  You
free str at the destruction freeing up the LAST allocated memory, but nothing
before that.
Something like that, yes.  :->
Yeah, at least compilers catch these.  :->
They aren't illegal, though, AFAIK.  I could be wrong.
[This one IS illegal]
That is pretty trivial.  :->

assistant: One other alternative is to go ahead and purchase the latest version of
Borland C++, which I believe is 5.0 and also purchase a good text editor
such as either Greenview Data's Vedit Plus or Luguru's Epsilon. Both of
these products are shipped with macros that implement a pretty decent
IDE using both their native editor and the Borland command line
compiler. I don't think that either of these solutions will easily
integrate the debugger like the Borland 3.1 IDE does, but they will make
for some decent edit-compile cycles. Of the two, I use Vedit Plus; a
co-op student who used to work with me swore by epsilon.

it. (only cost me $5.00)  Then I came across a whole package of Borland C++
3.1 books shrink wrapped for $2.50.  So, my questions are, is 4.0 or for that
matter, Borland a good place to start?  How much of a diffrence is there
between 4.0 and 3.1, will the books be close enfough to the software so I can
muddle thru it myself?  And, as I mostly use OS/2, how much of this
transulates to OS/2 platform, or for that matter, unix and unix type OpSys?

assistant: anno
    Must programs just use a table look-up for cycle redudancy checking.
    If you really want to know how crc works, here goes:
    You treat your stream of data as one huge binary number. You
    "divide" that large number by a 32-bit number (Most use a number
    that has been proven to catch more errors). The CRC is the remainder
    after division.
    EG (in hex)      3129487a987479812347987234810fffffaa / aaaaaaaa =
                     CRC value
    (message / seed) = CRC value
    This is not true division because its modulo 2 based, but you can
    make a table of every word and its remainder.
