RE: [Dev-C++] ISO C++ Compiler

[Opacki, J. <Jos...@ng...>]

Although I thought I had read somewhere that you could plug Dev-C++ to =
work
with Cygwin.  That would be very interesting for me to see.  If anyone =
out
there has done something like this, please share or point me to a page.

Thanks.

Subject: Re: [Dev-C++] ISO C++ Compiler


First let me point out that Dev-C++ is NOT a compiler, it
uses Mingw
(avalible at www.mingw.org) as the compiler, on top of
which Dev-C++ adds an
Integrated Desktop Enviroment (IDE).

As for mingw, I am not too sure about ISO but it is ANSI
compliant (I am
guessing they are similar at the very least). The thing to
watch out for is
the extensions that are avalible. Mingw is a copy-cat
version of the gcc/g++
compilers (avalible on almost all Unixes) that runs on and
generates win32
executables. As for the extensions they can be turned off
by using the
"-ansi" switch.

If you need any more information either someone else on the
list may be able
to help you or check out the Mingw web site.

[Dev-C++] using assert

[Wobien <wo...@pl...>]

Using assert is supposed to be a big help in finding bugs in your program.

#include <cassert>
assert(a<b);

should stop your program if a>=b and print the file and line number of the
assert statement that failed, if and only if you run in debug mode. If you
are not in debug mode, the assert statements should not be compiled.

Now I have 2 problems:

1: my program stops if the assert fails, even if I did not compile in the
debug mode.

2: when the program stops it does not wait and stop to give me the
opportunity to read the message about the file and line number. The system
("PAUSE"); statement at the end of the main procedure does not help here,
because the program never gets there.

A simple test "program" to try this is:

#include <stdlib.h>
#include <cassert>
int main()
{
    int a=5;
    int b=1;
    assert(a<b);
    system ("PAUSE");
    return 0;
}

Re: [Dev-C++] Overflow detection (was No Subject)

[Per W. <pw...@ia...>]

Are you also sick of the existing large-number libraries that exists, and
that supports any number of digits up to size of available memory?

To my knowledge, you can't write a portable implementation using
overflow exceptions. The normal method is for example to perform all
big-number arithmetic with unsigned numbers and a separately stored sign
bit.

Then you get:

r0 = a0 + b0;
overflow = r0 < a0 || r0 < b0;
r1 = a1 + b1 + overflow;
...

No need to work on bit level.

If implemented in assembly, the
  overflow = r0 < a0 || r0 < b0
can be ignored, since an overflow would result in the carry bit being set
in the processor flag register - all processors have support for carry
bit.

[Dev-C++] Overflow detection (was No Subject)

[David M. <ci...@ya...>]

No I don't require it to be standard, however I would like
it to be standard.

My current focus are speed and portability. The reason why
64 bit won't sufice is because I would like to take a try
at the RSA factoring challenge:

http://www.rsasecurity.com/rsalabs/challenges/factoring/faq.html

And if you look throught you will eventually find the
challenge numbers at 

http://www.rsasecurity.com/rsalabs/challenges/factoring/numbers.html

IF you take a look at those numbers then you will quickly
see why 64 bit is too small. Besides if I complete this
class I know at least 3-4 people who would use it because
they are sick of the 4 billlion limitation put on them.

Re: [Dev-C++] Dependencies in makefile

[<co...@ps...>]

Hi!

Make file doesn't consist header files
when you Build_All project.
Because all .o files are erased compiler have to build all again.

When you use Compile and make file doesn't consist headers
then probably you have checkbox
<MainMenu/Tools/CompilerOption/Use fast but imperfect dependency generation>
checked off.

Try check on, compile and check makefile.
Headers should be back.

Collins

Ok how are overflows handled in C++ for integer types?
I know about the resulting (number % upper_limit) effect which is
actually what I want. What I am interested in is determining that an
overflow has occurred.
So far my searches into the void ... whoops meant the C++ standard, seem
to suggest a exception is thrown when a overflow occurs, however I am
under the impression exceptions are not exactly completely portable just
yet, or am I wrong in this belief? The code makes use of classes so I am
fairly confident that exceptions are portably supported the question is
whether the exception is thrown for this exception. The following chunk
of the standard should explain why I am not too sure about this.
-- Begin Quote --
[Note: operators can be regrouped according to the usual mathematical
rules only where the operators really
are associative or commutative.9) For example, in the following fragment
int a, b;
/*...*/
a = a + 32760 + b + 5;
the expression statement behaves exactly the same as
a = (((a + 32760) + b) + 5);
due to the associativity and precedence of these operators. Thus, the
result of the sum (a + 32760) is
next added to b, and that result is then added to 5 which results in the
value assigned to a. On a machine in
which overflows produce an exception and in which the range of values
representable by an int is
[- 32768,+32767], the implementation cannot rewrite this expression as
a = ((a + b) + 32765);
since if the values for a and b were, respectively, - 32754 and - 15,
the sum a + b would produce an
exception while the original expression would not; nor can the
expression be rewritten either as
a = ((a + 32765) + b);
or
a = (a + (b + 32765));
since the values for a and b might have been, respectively, 4 and - 8
or - 17 and 12. However on a
machine in which overflows do not produce an exception and in which the
results of overflows are
reversible, the above expression statement can be rewritten by the
implementation in any of the above ways
because the same result will occur. ]

-- End Quote --
This seems to indicate that the overflow is only thrown on machines that

exception class exist for underflows the structure seems to be extremely
similar to the overflow, I assume if one works then so does the other.
Also is there some mathematical way to detect such an overflow? So far I
am not finding any way, as the result can potentially be anywhere within
the full range of numbers represent by the data type. I would rather not
try to determine if an overflow would occur by performing the addition
myself in binary as I am exploring this method to try to increase the
efficiency of my algorithm and doing the addition "by hand" would
severely increase the complexity of my algorithm.

hi Paul,

thanks for the reply.

Thanks.
I visited the website that was posted and I saw that it was quite different, 
the most notable bit to me was the different position of the target.

Thanks,

Re: [Dev-C++] InLineAssembler in Dev-C++

[Matthews <dem...@uw...>]

Yes.  *If* the VC++ asm blocks were allowed, the syntax would be like this:

asm {
	movd ptr [BigInt], eax
	add  dword ptr [SmallInt], eax
	movd eax, ptr [ResultInt]
}

BUT, since gcc doesn't allow blocks like that, you must use a strange
__asm() construct which I still don't understand and can't explain.

[Dev-C++] OT: The people behind the languages...

[Daniel G. <sp...@ho...>]

Hi all,
does anybody know how some of these programming geniuses got started? Are 
they all university educated or have some bravely fought their way up from 
the bottom (a bit like me lol).

I thought I'd ask, makes a change from coding queries ;)

[Dev-C++] "newer" Header files

[Michael D. S. <for...@hi...>]

In searching for two header files I needed, I was forced to download a 
bunch. Many of them have the same names as the Dev-C++ header files I 
downloaded (not to long ago) with Dev-C++ but are newer.

Any harm in using all the newer header files? Or should I avoid changes 
unless absolutely necessary -- like the two I was completely missing?

[Dev-C++] (no subject)

[David M. <ci...@ya...>]

Ok how are overflows handled in C++ for integer types?

I know about the resulting (number % upper_limit) effect which is actually what I want. What I am interested in is determining that an overflow has occurred.

So far my searches into the void ... whoops meant the C++ standard, seem to suggest a exception is thrown when a overflow occurs, however I am under the impression exceptions are not exactly completely portable just yet, or am I wrong in this belief? The code makes use of classes so I am fairly confident that exceptions are portably supported the question is whether the exception is thrown for this exception. The following chunk of the standard should explain why I am not too sure about this.

-- Begin Quote --

[Note: operators can be regrouped according to the usual mathematical rules only where the operators really
are associative or commutative.9) For example, in the following fragment
int a, b;
/*...*/
a = a + 32760 + b + 5;
the expression statement behaves exactly the same as
a = (((a + 32760) + b) + 5);
due to the associativity and precedence of these operators. Thus, the result of the sum (a + 32760) is
next added to b, and that result is then added to 5 which results in the value assigned to a. On a machine in
which overflows produce an exception and in which the range of values representable by an int is
[– 32768,+32767], the implementation cannot rewrite this expression as
a = ((a + b) + 32765);
since if the values for a and b were, respectively, – 32754 and – 15, the sum a + b would produce an
exception while the original expression would not; nor can the expression be rewritten either as
a = ((a + 32765) + b);
or
a = (a + (b + 32765));
since the values for a and b might have been, respectively, 4 and – 8 or – 17 and 12. However on a
machine in which overflows do not produce an exception and in which the results of overflows are
reversible, the above expression statement can be rewritten by the implementation in any of the above ways
because the same result will occur. ]
 
-- End Quote --
This seems to indicate that the overflow is only thrown on machines that produce some sort of exception when an overflow occurs. Also a similar exception class exist for underflows the structure seems to be extremely similar to the overflow, I assume if one works then so does the other.

Also is there some mathematical way to detect such an overflow? So far I am not finding any way, as the result can potentially be anywhere within the full range of numbers represent by the data type. I would rather not try to determine if an overflow would occur by performing the addition myself in binary as I am exploring this method to try to increase the efficiency of my algorithm and doing the addition "by hand" would severely increase the complexity of my algorithm.

hi folks,
i run dev-c++ ver 4.9.8.3 on windows 98.
i have a problem of having no compiler or linker errors whatsoever for a

Any thought?
