[Dev-C++] visual tool

[Vlada D. <dj...@im...>]

Hi!
I have recently started working with DevC++, and I find it good,
although confusing.My question is: is there any kind of visual resource
editor for DevC++? I=92ve heard about wxWindows, but I don=92t know if =
it
can do this.

I haven't heard of a 7 times activation limit in XP. Have you any
related link? (also it would be quite absurd).

But XP only lets you upgrade your hardware 7 times, each time causing you to 
phone up M$ and plead with them to give you a new licence key. After 7 times 
they decide that you must buy a new version of XP.

no?

Upgrade to XP. XP are not buggy. In fact they are better than Win2k

Half-right. XP is based on the 2000 kernel, and is very stable (compared to
what you're used to on '98). If you install 2000, you'll have problems with
games and DOS programs. XP has support for both, but some programs don't
work on it either. I, personally, recommend XP. It's stable and fairly
compatible. For those programs which don't run on XP, you can use '98 (XP
supports dual-boot).

RE: [Dev-C++] q??

[Ioannis V. <no...@ho...>]

Memory leak is when you allocate memory dynamically (on the free store) =
and you do not free it. You can avoid memory leak by using the standard =
containers instead of allocating and deallocating memory dynamically.
=20
=20
For example
=20
=20
Instead of writing:
=20
class A
{
 int *p;
// ...
 public:
A(const int x) { p=3Dnew int [x]; }
~A() { delete[] p; }
// ...
};
=20
=20
write
=20
class A
{
 vector v;
// ...
public:=20
A(const int x):v(x) {}
// ...
=20
=20
Instead of writing
=20
=20
int *something()
{
 //...=20
  int *p=3Dnew int[20];
 //...
=20
return p;
}
=20
=20
write
=20
void something(vector<int>&v)
{
 // store everything in v;
}
=20
=20
When the container reaches the end of its scope, it clears itself =
automatically.

There are various programs and libraries that help one keep track of
this sort of thing.

An email just came in and mentioned BoundsChecker:

<http://www.compuware.com/products/devpartner/bounds/>

There is also electric fence (efence) but I am not sure whether or not
that has been ported to mingw.

You may want to review this:

<http://netlib.bell-labs.com/cm/cs/cstr/123.ps.gz>

IIRC it contains a good primer pointers (found at:
<http://www.lysator.liu.se/c/c-www.html> ; contains general C info)

I think the goood idea is to use own containers that checks at program
termination that all prevoiusly acquired memory is properly fried...
well, to do that 'just' overwrite the new keyword... everywthing is
Brue Eckel's "Thinking in C++", just check: http://64.78.49.204/

That your memory in computer is deffective, and leaks bytes... check

You might be interested in Eckel's two books, Thinking in C++ volumes
I and II, especially II which address iterators although the whole
book is not yet complete:

Free versions are on the web at:

<http://www.bruceeckel.com/>

Analysis follows:

For information on the copy() function:

<http://wwwinfo.cern.ch/asd/lhc++/RW/stdlibcr/cop_4514.htm>

Apparently, copy just begins at one iterator and pumps each
iteration to the output iterator and both are increased.

We then need to look closer at the iostream iterators:

In <http://geneura.ugr.es/~gustavo/stl/istream_iterator.html> we see
the beginning of the definition of istream_iterator as:

template <class T, class Distance = ptrdiff_t> 
class istream_iterator { ... }

And ostream_iterator:

template <class T>
class ostream_iterator { ... }

from:
<http://geneura.ugr.es/~gustavo/stl/ostream_iterator.html>

So, I'd say that an iterator is made from ifile, and each iteration is
pumped to ostream with each subsequent iterator checked against the
same type of istream that did not have a istream passed into it's
constructor.

As to how copy realizes that it's at the end of the file, though, I do
not know because it is just checking that it's not equal to the
standard constructor's istream iterator which defaults to standard
input when an istream is not passed into the constructor. It may be
that this is a special propery of istream_iterator.

RE: [Dev-C++] Simple Question

[Ioannis V. <no...@ho...>]

The resulting source code after the preprocessing is where in the source
code was written PI to have been replaced with 3.1415 and where TWOPI is
written to have been replaced with (2.0 * 3.1415).
 
Then the whole code gets compiled.

Hi,
 
This is more of a general C question but just in case it's compiler
dependent. . .
 
I'm curious how the following is handled:
 
#define PI 3.1415
#define TWOPI (2.0 * PI)
 
Does this add a flop everywhere TWOPI is used or is the expression
evaluated to 6.2830 and then inserted?  If the latter, with what
precision is the evaluation done (e.g., what does TWOPI look like if I
#define PI to 20 digits?).
