Re: [Dev-C++] structs

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

Maya - try compiling your examples :-)

This is a construct that is affected by language.

In C:

struct Human {
...
};

Require you to always declare your variables as:
struct Human a_human;

In C++ - together with the addition of the class keyword - you can get
away with:

struct Human {
...
};

Human a_human;

or
class Human {
public:
...
};

Human a_human;

So basically:

typedef struct Human {
...
} _Human;

declares a structure named Human, and typedef this struct to the name
_Human.

In C, you can then declare a variable as either of:
struct Human a_human; /* referencing the name of the struct */
_Human a_human; /* referencing type typedef name */

while in C++ it doesn't matter. It is even possible to define the data
type as:
typedef struct Human {
..
} Human;
i.e. same name for the struct declaration and for type typedef.

No, it is not true. In fact this doesn't even work.

Re: [Dev-C++] structs

[Maya <Esc...@ne...>]

In the first one you have declared a struct named _Human and 
instantiated it right after the declaration with name Human. In your 
program you can just say for instance: " Human.height = 1.70 " and it 
will work
Here is another example:
typedef struct _Human {
  int height;
}Human;

int main(){
std::cout << "The Human Project" << std::endl;
std::cout << "How tall are you " ;
std::cin >> Human.height;
return 0;
}

In the second example you have declared a struct named Human, but has 
not yet been instantiated.
Your code would look something like this

struct Human {
 int height;
};
int main(){
Human human; // Instantiating the Human struct
std::cout << "The Human Project" << std::endl;
std::cout << "How tall are you " ;
std::cin >> human.height; // <<==
return 0;
}
Which one is better? it depends on the program you are working on, really!

Hava a good one!

Hi, from my experience, starting programming is a better way to learn
the programming language than reading books, besides you'll have to
deal with all the error messages later even after you have learned the
language, and you'll get a lot of error messages (no joke), and as long
as one of thousands of errors remains, your program don't compile.

The best resource I've found for practicing C/C++ programming is
programming in GTK. It is Linux based, and very straight forward and
intuitive. After you've been familiar with GTK programming and
conquered your thousands of errors, you are already pretty good at
C/C++. The GTK's official website has a very good tutorial.

There's another website called something like "C/C++ Frequent Asked
Questions", which is very useful because it has a very big list of most
of the mistakes people make when programming with C/C++. They also
compiled a book with the same name for sale, but the website has more
information because it's updated. Sorry I forget the website's address,
but if you search the book's name on amazon.com you should be able to
find that website.

That's my opinion. Besides, the more I program, the more I think it's
the design that matters, not how well you memorize the language,
because it's the final product that counts, and good design has a
better chance of making a better final product than being proficient in
that language.

Bye.

Jack

Re: [Dev-C++] Neoengine devpak and tutorials

[<de...@ci...>]

UDTVectorEXPIMP looks like it is probably a template  definition.

So somewhere in the code someone is saying something like:

UDTVectorEXPIMP fred;

where it may be that it should be

UDTVectorEXPIMP<int> fred;

The exact details of what's needed can only be known from finding the 
definition of UDTVectorEXPIMP to know how many parameters it expects.

Also you need to be sure the instance is actually new-ed. If the instance
is an automatic or static variable callinf "delete this" will have undefined
behaviour, probably bad.

If you want to "delete this" you are recommended to have private
constructors and destructor. Use a factory method to create objects.

Re: [Dev-C++] fustrations in c++

Religion has not value in the science realm. Religion is based on faith, 
and the absolute value of it is the corner stone of any religion. 
Science on the other hand makes no attempt to apply faith to any of its 
certainties, or lack of it for that matter.
Please leave it at that, don't pursue this issue any longer. I realize 
this topic is important to you, but it is taking space in a mail group 
that does not deal with that area of life. I would *very* strongly 
suggest that you move this line of emails to either a personal [email to

In other words, knock it off kids!
Have a good one, and if you are going to have more than one.... give me

RE: [Dev-C++] Abnormal program termination

[Nicholas O. R. <exc...@mi...>]

By "well-spaced code" I just meant my code had plenty of white space between
variables, operators, etc.  For example, I would call this well-spaced:

for ( int i = 0; i < 6; i++ ) {

	float temp = array1[i];
	array1[i] = array2[i];
	array2[i] = temp;

	cout << "I just swapped ";
	cout << array1[i] << " and ";
	cout << array2[i] << endl;

}

But not this:

for(int i=0;i<6;i++){
float temp=array1[i];
array1[i]=array2[i];
array2[i]=temp;
cout<<"I just swapped ";
cout<<array1[i]<<" and ";
cout<<array2[i]<<endl;
}

It shouldn't affect the behavior of the program at all, aside from bloating
the size of my source files.  It's mainly just me being a neat freak.

Re: [Dev-C++] OT: A Good C++ Book ?

[<ca...@kr...>]

hi Sami,

> Thanks in advance for the suggestions.

hmm.. not a real suggestion but a thought.
besides the kernighan and ritchie I quickly learned some c with the
nitty gritty c book from addisson and wesley.
I looked through some books of this series and the c++ one also looked
very promising for quick lessons and learning.
accompanied by the before mentioned bjarne stroustrup for in depth
informations this should be a good couple.

I also advice for the secure programming cookbook from o'reilly!

1300 lines?  Uh, no.  That's not the problem.

If the error is sporadic like that, it's usually a pointer error or some
sort of memory overwrite.  Missing copy constructors will do that.  Modify
your program to log error messages to a log file and try to pinpoint where
the error is happening.  Segment fault errors are sometimes hard to
recreate and you'll need to be patient and run lots of test cases.

HTH.

These are the remnants of the C world. The difference is only noticable=20
in C. With the second version in the C world you had to write this to=20
declare a variable (a Human struct):

struct Human MyHuman;

However, with the first one (as Human is a new type in this case), you=20
could write this:

Human MyHuman;

So in the C world, you spared the struct prefix at variable declaration,=20
and saved yourself a lot of typing.

In the C++ world, this is no longer relevant, as struct automatically=20
defines a new type (like class).

Re: [Dev-C++] Abnormal program termination

[Zonnet <gko...@zo...>]

Hi Nicholas,
I think you should look into dependencies. It might happen that some
files are compiled and other are not. The linker will not always
complain about this. This means that some functions/methods that are
called are really of the wrong signature and make a mess. This can cause
such crashes. Either: re-compile the whole lot always or try to find out
how to properly set-up dependencies. I'm not sure sure about the support
for dependencies in DevCpp, can anyone, please, comment?
wkr,
Gerke

[Noorez K. <coo...@ho...>]

what is the difference between these two

typedef struct _Human
{
   int height;
}Human;

struct Human
{
  int height;
};


and in the first one, what does 'Human' mean at the end? In both structs u 
can declare a Human type, even without the Human thing at the end in the 
first one

Hmmm. I am a bit puzzled. Could you tell which one is this OO library?
Who must derive from/delegate on CGObject? Or it is a Policy class, that

This somehow reminds me of the problem with having  a

implementations forbid this.

Well, I use it at home with Gentoo (yeah I know, this is not fair play),
and at work we have sort of 'patchwork Debian Sarge' and it works quite
well also. To say the least I am truly impressed with both the default
valgrind 'skin' and the calltree one ( and the humble KCachegrind
program beats Rational Purify crap everywhere, every time). I don't
aspire to get KDE programs run smoothly on Cygwin ( I tried it and I
find quite boring to wait for widgets to repaint each time a dialog box
pops up HIDEing and EXPOSEing whatever it has below :( ), but valgrind
used from commandline would be a nice asset to add to Win32 debugging
tools.

Re: [Dev-C++] Abnormal program termination

More then likely, you have a pointer problem somewhere. ie: You forgot to
dereference a pointer before writing to it. Errors in pointer use are the
single most common cause of of these kinds of errors in Windows.

RE: [Dev-C++] OpenGL with Glut blues...

[Daniel W. <dan...@ta...>]

Thanks for the suggestion Scott.  It's pointing to the proper bin in
Dev-C++ in the compiler options. =20

I tried going through the compiler options and found nothing but the
default listed and the G++ directory within the include file. But, I did
notice that I had set Dev-C++ to create a Project for C++ so it made a
resource file with that in it to link the icon.  I took it out and still
got the same message. =20

So I decided to try another example from scratch.  The hello C.  Upon
creating a project I chose the OpenGL for the project, linked the glut
file, but I am still getting the same message...=20

gcc: Compilation of header file requested
gcc: file path prefix `C:\DEV-C_~1\Bin\' never used


This is the hello.c example at this link... =20

http://www.opengl.org/resources/code/basics/redbook/index.html


Is there a newer version of the glut that I should be using?  I went to
the Nate Robins site and downloaded the (everything you need to get
started with glut) link.  Do I need to use the glut32.dll as well?
Should it be in the G++ file within the Include directory? =20

Any other ideas would be greatly appreciated,=20

There is no order they need to be in. However, I think it helps to sort
them out. I list custom headers first, then library headers, then C++
headers, and finnaly C headers. It looks like it is saying that one of
the headers has C:\DEV-C_~1\Bin\ in it. All of the headers aren't there.

Go to Tools -> Compiler Options. Then, click on the Directories tab.=20
Next, click on the Libraries, C Headers, and C++ Headers sub tabs and
make sure C:\Dev-C_~1\Bin or anything like that is in one of those
fields.

Well that's strange. Could you post <Dev-C++>/include/neoengine/base.h=20
so I can take a look at it. That can be the only source of the problem,=20
but with the 0.7.0 devpak it shouldn't be.

Well, I haven't read any myself, so I don't really know which one is=20

You might want to join the forums on http://neoengine.sf.net and post a=20

"Well-spaced code" or "Agoracode" is code that has lots of room on the disk.
And has its own little pharmaceutical setup.

As opposed to "ill-spaced code" or "claustrocode", which resides on a full disk.
And is sober.

HTH.

Re[4]: [Dev-C++] "delete this" in the class member

Hello Miguel,

  This library is GTL. http://www.gtl.kis.ru/bin/GTL10R8.exe
  This class with "delete this" is the template parameter of
  pointers "container" class. (see line #33 /Source/Gobject.cpp)
  This library is based on MFC :-(
  Therefore i have no plans to use it in real work, but some design concepts of this
  library are interesting(and may be some of them are dangerous :-) ).

  Yes, it will be useful tool.
  Among similar tools under Win32 i have used only CodeGuard (comes
  with Borland C++ Builder 5 or later(may be)).
  Valgrind under Win32 can be a good open source replacement.
