assistant: On (23 Jul 97) Thomas Maeder wrote to Cameron Clark...
I participated in a benchmark on the speed of exception handling about a
year ago or so.  Overall, the speed was found to be far less dismal than
expected -- while exiting from some level via an exception was
relatively slow, it frequently wasn't much (if any) slower than creating
a code to indicate the error, then exiting via multiple levels of normal
exits back to the point that the error could be handled.  The exact
difference in speed often depended upon exactly how many levels there
were between the exception and the handler.  If there were very few
levels, normal handling tended to be faster.  If there were many levels
between the two, exception handling tended to be faster.

assistant: there is *no* magic way for that. you have to do it by hand. like, if you do
unsigned a+b and the result is smaller than either, beep. but for larger
formulas it's much more complex, and it might become a pain. Make a class of
numbers that checks everything and throws exceptions, or such.

Write your reply.

assistant: As far as I've seen, defines are inline replacements done at compile
    time. Constants are usually in memory.
    To test you compiler. Create an a constant array of bytes and use
    lower funtions to move characters using the address of the constant
    array. Print the array. You can do the same for a list of constant
    bytes. Move 2 bytes to the address of one char and print that char
    and the next char to see if the values change.
    Note that there may indeed be basic block optimization that uses
    the value of a constant rather than the address of a constant, so,
    you can't be sure if the value is used as an operand or the address
    is used.

    I've a friend that recently graduated with a CIS major and went to

    of COBOL still (along with some SQL(?) like language for file IO).
    I _assume_ that since Borland added the microsoft foundation classes
    along with their OWL, Borland has conceided to the MS giant's version
    of foundation classes. In other words, weeding out support for their
    version because of the popularity of VC++ (eg: PC Magazine uses only

Write your reply.

assistant: On (25 Jul 97) Steven Dyck wrote to All...
No, they're not.  Headers are nearly always specific not only to the
compiler, but to the specific version of the compiler you're using. If I
sent you, say, the iostream.h from BC 4.5, TC++ 1.01 wouldn't be able to
compile it at all.
On top of that, headers are consistently copyrighted, so anybody who
sent you a copy would most likely be breaking the law.  (The only
exception would be if the person sending the copy lived in a country
with no copyriht laws, or with laws that didn't conform to the Bern
Convention.  In any case, you'd be breaking copyright laws if you
attempted to use what they sent.
You're probably going to have to re-install the compiler from the
original disks.  If they're damaged, you _might_ be able to get Borland
to send you a replacement disk.
However, if humanly possible, I'd suggest getting a newer compiler.  C++
has progressed _considerably_ since 1990, and much of what you see, hear
and read about C++ simply won't work with this old of a compiler.  What
you'll learn using it can't really be considered C++ any longer, and
honestly (if my memory of TC++ 1.01 is at all accurate) never really
could.  TC++ 1.0 was (obviously) Borland's first attempt at a C++
compiler.  While it was a reasonable first attempt, it was severely
flawed in a number of ways.

Others fail to grasp that this echo is devoted to C++, not philosophical
discussions of the definitions of "odd", "even", "positive" and so on.
We all know how 0 acts when we add, subtract, multiply and divide it.
The only question, then, is what words you happen to feel apply to those
behaviors.
Differences (if any) between the way 0 acts in math, and the way 0 acts
when used as an integer value in C++ would certaily be relevant in this
echo.  The words you feel like using to describe either of these sets of
behavior really aren't.

assistant: On (26 Jul 97) Darin Mcbride wrote to Kevin Campbell...
I'm hard put to agree that lack of source code is a minor detail.
However, I'm interested in knowing exactly how they're distributing STL
without source code.  Nearly all versions I've seen are distributed
primarily as a set of headers.  There's (presently) little or no other
reasonably portable method of handling templated code.  Some specific
compilers have ways of handling it, but most still need source code
around in some form or other to work correctly.
Not in my experience.  This obviously depends somewhat upon the specific
implementation of STL you work with, as somebody can write an
arbitrarily poor implementation.  However, my own experience has been
that the variation has been much wider than the numbers above suggest.
Some of this depends on exactly what you compare though.  For instance,
STL uses one ownership policy, which can involve creating and destroying
quite a few objects.  Many situations don't really require that, and can
gain _considerable_ speed by avoiding it.  (I've got one that more than
tripled in speed when STL was replaced with more specialized code.
However, STL is nearly always good enough to at least use for the
prototype, and is only worth replacing when you find that it's a cause
of a major bottleneck.  This was the case with the code mentioned above,
but certainly is NOT the case in LOTS of other code I've dealt with.

Hola Christian,
  You need to use forward declarations.  There is no 'typename' keyword
in C++.  What the compiler is telling you is that it does not
recognise  the symbol as a typename, but it NEEDS a typename!  You need
to do this :
//  Forward Class Declarations
class A ;
class B ;
//  Actual Class Declarations
class A
{
   A(int a) ;
   B func1();
}
class B
{
  B(int a)  ;
  A func2() ;
}
//  From here on define your functions in a seperate C++ file or with
the  //  inline keyword in your header.
Best of Luck
