Re: [Dev-C++] Where to include files

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

Guard statements are lines like these in your header files:

#ifndef FOOHEADER_H
#define FOOHEADER_H

int foo;
char *foostring;
//...

#endif

Then if two files include foo.h, it won't be recompiled because FOOHEADER_H
has already been defined.

Re: [Dev-C++] Where to include files

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

Ahh, I see where you are coming from.

What those statements won't quard against is compiling files that
simply aren't required.

e.g. If your class uses math.h you would only include it in the .cpp
file. This prevents any .cpp files that include your header from
having to compile in math.h (unless they include it themselves).

I don't believe the question posed is how to prevent multiple
inclusion, if I mis-interpreted then your answer would work
perfectly.

Re: [Dev-C++] Where to include files

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

As far as  I know there are no "rules". However here is my rule
"Include in
the .cpp, if it gives you errors put it in the .h".

The main reason you don't want to put it in the .h is because the
header
will be included in EVERY single file that includes your header and
(this is
the killer) is recompiled every time one of those files is
re-compiled. If
the header is in the .cpp then it is only re-compiled when the .cpp
changes.

Of course if you have some super computer avalible then this reason
goes out
the window. If you don't then this is about the only reason I can
think of.

Re: [Dev-C++] Want some help for a c++ beginner.

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

I found DEV to be excellent for learning C++, but if you then move to visual 
studio and microsoft's version of C++ (I am exaggerating) then it can be a 
little confusing with templates.

But do not worry, you will not go wrong. And post your questions to the 
mailing list - I need to get better at C++ also!!! (too much cross-language 
work!).

[Dev-C++] Where to include files

[Glen V. <gve...@pa...>]

Hi, I was wondering where I should best place my include files.
Suppose I have a class testClass which needs to include a couple of files.
Should I place the include-statements in the .cpp files or in the .h (so 
one could see which files are needed?)?
Or does it depend on the circomstances? For example: include-files which 
contain the type of declared members in the header, and include-files 
needed for the implementation in the .cpp file?
Are there rules, or am I free to choose?

Please enlighten me :-) .

Re: [Dev-C++] Want some help for a c++ beginner.

[Hossein H. <ult...@em...>]

Dear lavaspan,

>I am a beginner, but I am learning.
Good Luck!

> 1.Is Bjarne Stroustrup's The C++ Programming Language suited
> for a beginner?

Yep! But not as the first text. In my idea, the best book as a
first text is: "Accelerated C++", just take a look at:
http://www.acceleratedcpp.com

Anyway, after reading the first text, I recommend TC++PL, and a
look to the two other famous "general purpose" C++ books, i.e.,
"The C++ Primer," and "C++: How to Programme". (Look for the
latest versions.)

> 2.Which c++ complier is recommended for learning pure c++?

There are not so much options, but GCC, Comeau C++, and Intel C++
are the most Standard compliant ones. (Don't forget that there is
no fully Standard compliant compiler.)

Hmmm... It completely depends on your purposes; If you want to do
things which I call "Developery stuff," you've got to bypass deep
issues in C++. If not, then there are enough stuff to consider in
C++ itself.

> 4.Is Dev-c++ a good tool for learning c++?

Yeah, I believe.

It again, actually, dependes on your needs and interests. As I
told, there are enough stuff to focus on in C++ itself. But you
can, as well, get into the different applications using C++.

[Dev-C++] Want some help for a c++ beginner.

[lavaspan <lav...@ey...>]

I want to get some help for how to learn c++ as a beginner. For me ,it is
really important to get some advice because I am just learning c++ by mostly
myself, escept for some information form the Internet, without out any further
helps specifically for me. I have got some books published in English, but you
know, English is a foreign language to me. I don't think that I can understand
all the points in my self-learning course,so for now I cannot say what I
really want.The several upcoming points are some questions that I am majorly
want to get, so if anybody who can give me some help, or who has some
experience in you past learning periods, please mail to me.

If not to bother other people, please mail to me at lav...@ey...



I am a beginner, but I am learning.



My questions:

  1.Is Bjarne Stroustrup's The C++ Programming Language suited for a
beginner?

  2.Which c++ complier is recommended for learning pure c++?

  3.I don't want to use some popular comercial c++ development tools such as
Microsoft's Visual C++ or Borland' C++ Builder. Is learning basic c++ concepts
a good idea, or how about straightly learning those popular tools?

  4.Is Dev-c++ a good tool for learning c++?

  5.After I have learnt those basic concepts, by which way I shoud get further
concepts? For example the concepts about Windows applications development.

Would you accept "start using wxWindows then you can have more intelligent
assert processing / logging" as an answer? ;-) Thereagain, you are using C and
not C++ so that may not be such a good answer anyway.

Re: [Dev-C++] using assert

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

Thanks Daniel and others for your suggestions.

The #define NDEBUG suggested by jo mateix works fine to prevent the
assertions to compile.

I already tried to run my program from the DOS prompt, but I did it by
closing Windows and start computer in DOS mode. When I do that I get "This
program cannot be run in the DOS mode".
When I do it the way Daniel suggests it works fine, and I can read the
message.

I'm not sure if they do not like to be compliant (except for MS
implementations). But, AFAIK, the problem is that beeing 
completely compliant is not that easily feasible. Read the
following article written by Herb Sutter: "C++ Conformance
Roundup". (I couldn't find the link according to the server
problems, but take heart and search for it!)

> There is some one?

Unfortunately, no!

> There is a project of something like that?

Hmmm... Every implementation (by default) wants to be compliant
to be more widely usable. So there are lots of them!

> Why the GNU compiler is not one?

They're one of the ones trying to achieve that.

[Dev-C++] Optimization: Gcc/MingW vs. MS VC++ 6.0 - Any experiences?

[stefan k. <ste...@ya...>]

Hi list!

This question goes to the more experienced devs on this list:

Has anyone of you made performance tests comparing the code optimization 
results of the MingW compiler with what you can gain with MS VC++ 6.0?

I'm especially interested in multimedia performance tests - processing 
large buffers of 32bit floats, computing complex floating-point 
algorithms, moving large blocks of memory, etc.

MS VC++ 6.0 does a fairly good job optimizing the output code, only 
beeing beaten by the Intel-C++ compiler in some cases.

Anyone having any figures where Gcc/MingW optimization stands?

Best,
Stefan

I myself don't know how, but I've heared that XML has got stuff,

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

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

Frank,

My experience so far has been with VSC++, and now Dev-C++, in which I =
prefer
Dev-C++ over the M$ product.  Unfortunately my experience has been =
limited
to Windows and I am only starting to branch out into the Unix/Linux =
markets.
Cygwin is a good choice for me since I won't have to forfeit my windows
environment, however, command line compiling and writing my own make =
file is
foreign to me.  When I read the you could tie Dev-C++ into Cygwin and =
use
g++, I wanted to get as much information as I could.

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++

by using the

RE: [Dev-C++] conio

[P.D. v. Z. <pa...@my...>]

What kind of advice is that? :|
Do you know anything about C or C++ at all?
C does not know about the concept of namespaces, so "using namespace std"
would only generate an error.
As for the C++ "#include <conio>", this will not work either. conio is not,
never was, and never will be a standard header, and trying to include it in
the C++ header fashion won't make any difference whatsoever, you'll still
get errors.
And of course, conio.h isn't a standard header for C either, so the chances
of "#include <conio.h>" working are small too. MingW provides a contributed
(and broken) conio implementation, because so many Borland and Microsoft
users think this header is standard, and come crying to the lists when it
doesn't work on a standards-compliant compiler.
My advice is to avoid conio at all costs. For Win32 you're much better off
using the Win32 API to accomplish the same tasks (positioning the cursor,
etc), and for true DOS console manipulation you should be using a different
compiler (try DJGPP for example), because MingW is for Win32, and creates
only Win32 executables. You could also look for a "curses" implementation,
which tends to be a bit better at cross-platform compiling, and is a true
third-party library, not something people expect to be standard but isn't.

Regards,


Paul

Re: [Dev-C++] using assert

[jo m. <non...@ho...>]

I don't know what you mean by "compiling in debug mode", but if you want the 
"assertions" not to be compiled I think you should

#define NDEBUG

either in the source code or trough the command line.
I hope it helps.

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

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

Ok, point taken. I am not going to stop though. For me this
is another of my
personal projects that help me learn. Guess I will point
them towards GMP
and the Large Number class on sourceforge.net (a class I am
fighting to
understand as I see alot of pre-processor directives).

No assembly! I am fighting for portability, asm is one of
the fastest ways
to break that portability. Damn, I am such an idiot. That
would work
extremly well! Thanks! The only difference is I add the
overflow to the next
block. The only bit I was worrying about was the carry bit.

Thanks Per

Re: [Dev-C++] using assert

[<qa...@ho...>]

1) I have no idea if the 'assert' function only should be compiled in=
 debug-mode so I can't help you here.
2) When an assertion fails the program exits with an errorcode, this is the=
 normal behaviour and as a result your window gets closed.
The only way I know of to work around this is to start the program from a=
 dospromt, and not from within Dev-C++.
