[Dev-C++] using iso646 (words for symbol of bit operations)

[Carlos d. M. <cg...@wo...>]

I saw a contest I thought iteresting to do, I wrote this:

This compiles:
#include <stdiostream.h>
#include <stdlib.h>
#include <math.h>
#include <iso646.h>

short int compare(const long int, const long int);

int main()
{
long int a = 45, b = 54, x = 3, y=3, m=56, n=32;
int res;

printf("%ld-%ld= %hd\n%ld-%ld=%hd\n%ld-%ld=%hd", a, b, compare(a,b), x,
y, compare(x,y), m, n, compare(m,n));

system("PAUSE");
return 0;
}

short int compare(const long int first, const long int second){
long int res1, res2 = 2, res3, unsi;
short int result = 0;

res1 = second - first;
res1 >>= 30;
unsi = res1 ^ res2;
res3 = second - first - 1;
res3 >>= 30;
res3 ^= res2;
unsi &= res3;
result = 2 - unsi;

return result;
}
-----------------------------------------------------------------------------

-----------------------------------------------------------------------------

This don't (variables of the function are considered not declared from
line 25):
#include <stdiostream.h>
#include <stdlib.h>
#include <math.h>
#include <iso646.h>

short int compare(const long int, const long int);

int main()
{
long int a = 45, b = 54, x = 3, y=3, m=56, n=32;
int res;

printf("%ld-%ld= %hd\n%ld-%ld=%hd\n%ld-%ld=%hd", a, b, compare(a,b), x,
y, compare(x,y), m, n, compare(m,n));

system("PAUSE");
return 0;
}

short int compare(const long int first, const long int second){
long int res1, res2 = 2, res3, unsi;
short int result = 0;

res1 = second - first;
res1 >>= 30;
unsi = res1 xor res2; <-- line 25 not declared
res3 = second - first - 1;
res3 >>= 30;
res3 xor_eq res2;
unsi and_eq res3;
result = 2 - unsi;

return result;
}

Yes, I know there is people who do not like systempause.

> Great! As you see it was not a compiler's issue.

Great! Yes!
Now I've found and reviewed one piece of code which has the for(int i) I
said it didn't work. It is an author error (author of some code example I
used). The ANSI about declaring for is something like "you can declare
inside a for statement in the way (int i = 0[...]), but you can't use it
later outside it, if you want you have to declare it just before the for:
int i; for(i=0[...]) or redeclare it".

I read first C/C++, an old edition and centered in C, so it said nothing
about possibility of declaring in the for.
Later I bought the "C++ how to program" (which couple of inexactitudes I
found, some misleading things about bitfields, I suspect are due to the
translator (I bought it in spanish) who knows bad spanish (!!!)), but I knew
for, and I only noticed "can be declared in", but not read "out of it it is
out of scope". And later I got some code examples from some sites (I don't
remember where) where they were used later, and that misled me, thinking
that the error wasn't only outside, but inside, too.

It's a bad thing that the last for/while rare thing is deleted. I would see
a possibly frequent error. (or you a compiler strange behavior, hehehehe)
and I would learn to see a error now I am unable to see (Feel I need a
phrase about the sea being free).

The two bad comments were not in the original, I added them in the
message. The // was an explanation for you about where the fail was, and
since I write almost everything in C++ now I use //always. If so the
compiler would have say errors errors errors!!! and bad comment. The
other that interrupts is either added in the message (sorry, I had to be

I had to notice they would give you errors if you try).
Yeah! Those damned \n. I forgot that this experiment was the last before
abandoning that custom of \n in scanfs (it was my second experiment
while learning programming) and that I deleted the correction and left
the original with \n (I did not reached to try the correction which
works fine). And so I was not observant of that error, when I saw a \n I
thought "printf"... and went on.
Without it it works fine.
All the other strange behavior (or possible strange, of course) are
corrected and I don't have any of them at hand.

There's no need to do that! The compiler can generate readable assembly
code for you.
Add -S to Project Options->Compiler Options. Linking will probably fail,
but you will see the assembly code in the .o files.

Although widely used, fflush(stdin) has undefined behaviour. fflush() is
made to work with output streams, not input. So it may crash  your PC or
cause some  acccident. You do not want that, do you?


So if you want to flush stdin you have to use something like that:

void stdinflush(void)
{
  
  while(getchar()!='\n')
     ;
}



A working example:

#include <stdio.h>

void stdinflush(void)
{
  
  while(getchar()!='\n')
     ;
}


int main(void)
{
  char c;
  
  scanf("%c", &c);
  
  stdinflush();
  
  printf("\nYou entered: %c\n", c);
  
  return 0;

}  



Another thing is that scanf() is dangerous and should be avoided if
possible.

Here is an old experiment for programming, when I still did not know

There are two lines, in red, that invert their order, the scanf is done

Re: [Dev-C++] problems with linker/headers

[<Met...@ao...>]

I got such the same problem, when I try to compile and run some of my window 
based projects, telling DevCpp to generate a console for debugging purposes. 
At this time, I must tell the linker to "include" some of libs to get my 
program running, otherwise I get "cannot link to..." linker errors.

In the cas you are telling us, if you talk about "CreateBrushIndirect" API 
func, you must tell the compiler to link with gdi32.lib. Make sure you have 
the -lgdi32 command in the linker option edit control, in project options 
window.

Send me a zip of your projects file, I might see what's happening and help 
you.

Yes, scanf() is a very dirty function to use (because of the buffer
mechanism)... it should be used only for the most quick-n-dirty programs. In
more 'complete' programs, the safest thing to do would be to read into a
buffer (using cin.getline() or gets()) and then parse it manually.

So the compiler's fine, it's your code. Also, in the for(), while() thing
that Carlos had written about, I'm pretty sure it was a syntax error or
something. It happens very often, and when you read it for verification, you
tend to miss it, because you're expecting something, say a semi-colon, and
you come across a colon, and the eye's in-built error correction routines
fix that :). There's the classic example of counting the number of 'F's in
this sentence:

FINISHED FILES ARE THE RESULT OF YEARS OF SCIENTIFIC STUDY COMBINED WITH THE
EXPERIENCE OF YEARS

Most people count three, but there are actually six (you tend to miss the
'OF's). A computer would count six perfectly. Proof that intelligence isn't
exactly good? <shrug>

The best thing to do when you have an error and you're sure it's in a line,
but you can't find it, is re-type the whole line.

Peace.

Depends on what kind of monitoring to you want.
The simple monitoring is no of packet send / recieve and this wou can do 
by click on open connection :-) in system tray.
For more treffic control / monitor you need a firewall so to write a 
firewall is compicated and you need to read DDK form
microsoft
http://www.microsoft.com/ddk <http://www.microsoft.com/ddk> because you 
need to write a driver so isn't so easy afterall.You must write a driver 
below all protocols an up on netwoark card (modem whatever)
so download a firewall eg zonealarm (serach on google i don't know the link)

The control string in a scanf() call can be one of these 3 types:
- format specifier
- white space
- non white space

When you use a control string like "%d,%d", scanf will read an int, read and
discard a comma, and read another int.
Same happens with your "%d\n" control string; it will read an int, then read
and discard a new-line caracter.
When scanf() can't find the non white space caracter, it normally finish,
and some caracters can remain in the keyboard buffer, so it will mess with
another scanf() calls if you don't use fflush(stdin) before them.

incorrect :-) )

You're writting all in lowercase, but compiler (linker etc) is case

yes, it is. line is a string. In an ifstream. 
Some Book examples uses my kind of getline e.g.

[Dev-C++] problems with linker/headers

[philip r. <ph...@ro...>]

hi

I'm puzzled.  I've been making some simple Windows apps  (running Win95 =
on an  old but otherwise reliable and virus -free machine).  For a while =
they compiled and ran OK but then they started coming up with linker =
error messages - particularly inablity to find definitions which should =
be in windows.h (actually in wingdi.h,  I think) - such as undefined =
'getstockobject',  'createbrush', 'selectobject' etc.  I've tried =
reinstalling DevC which works for a while but the same problem recurs =
and it's now pretty ineffective.  Sometimes pasting the original source =
code into empty projects also worked - but that's tedious and it's also =
become ineffective.  A few programs from the 'Examples' folder still =
compile and link successfully.  I'd be grateful for any suggestions.

Thanks
Philip

[Dev-C++] strange behavior

[Carlos d. M. <cg...@wo...>]

Here is an avi showing the execution of the pogram form the message
"compiler psychiatrics"

[Dev-C++] compiler psychiatrics

[Carlos d. M. <cg...@wo...>]

Here is an old experiment for programming, when I still did not know
C++, (only a piece of the program, so I don't get you buried under a ton
of code). You run fine?

There are two lines, in red, that invert their order, the scanf is done
before its printf.
printf("and then choose the weight\n");//THESE TWO LINES CHANGE THE
ORDERING!!!!!
scanf("%d\n", &weight);

You see (adding two lines before)

___________________________________
| Title                                                       _0X |
|-----------------------------------------------|
|  [...]                                                               |

|  Choose the height.                                        |

|   _                                                                 |
|___________________________________|
The program asks for the height, you enter the height you want, 180, and
then you wait the next prompt for the weight, but you find there is the
cursor one line below, waiting your input...

|___________________________________|
And you enter any number, then the prompt appears, and from now on all
inputs are before its prompt. When the moment arrives when the program
prints your character's statistics you see what went where. It continues
doing so till the end.
Copying the scanf after the printf and having two scanf only makes the
error repeat in the next pair printf/scanf

The best is that it happens when I compile it with borland 5.5.

P.S.- Sorry for my firsts shaming posts at this list, a year ago, more
or less, I regret having written so big stupidities, as I wrote those

should be in an older message, when the referenced messages were
remembered).

Thank you all

[Dev-C++] problem with getline()

[<h.r...@gm...>]

Hi list,

sorry, i know its bad style to ask nearly the same question twice, but i
make no progress with this problem. All in this file works well, except the
getline command. Allways the program crashed at this point. No exception, no
message, nothing. Has anyone a idea ? 
Thanks in advance !!

[Dev-C++] monitoring traffic, how?

[Zodiaq <zo...@ac...>]

Hello all Dev-C++ users and other hackers,

  Something very strange happened to me recently and then I've decided
to write small app to monitor how much data is being send and received
by my computer... I looked at MSDN, Platform SDK and some other sites
but couldn't find how to do what I want... this propably can't be
socket functions because these are only for creating and destroying
connections TCP and UDP... TAPI propably not because these are all
about Telophone lines... so where to start? How to monitor TCP/IP
trafic? Well for now I just want to get only butes send per second and
received per second... I don't want analize datagrams or something
like these... Any help?

-_-_-_-_-
regards, Zodiaq...

Ahh, it's unfortunate but it is close to useless. C++ has become quite
different since then. You have to get the 3rd or special edition...

Visual C++ 6 is very old and not ANSI C++ compliant... You should learn
about VC++ 7 .NET (that's what i am also learning this time).


From the series of those books, i have the "Beginning Visual Basic 6"
which is useless too (VB 7 .NET is quite different than 6).
