hi all, i'm a beginnere so this should be a simple question. What is a parse
error? When I put:
cin>>a; 
after the Add() function declaration, Dev-C++ gives me an error, here it is:

18 func.cpp | parse error before `>'
Can someone help? Thanks!

RE: [Dev-C++] Basic C question: scanf

[Luigi S. <gi...@li...>]

In my opinion you should use the solution suggested by Nurhidayat (I mean 
compare the value returned by scanf with EOF, see below), in fact this 
allows your code be used like a "filter".

Just in case you are not familiar with redirection and pipes, here is what 
I mean.

Suppose you wish to input these values: 100 200 300
You could feed the values via console (as you usually do) or by the 
following two steps: (I assume that you are in a DOS box, and your 
executable is named salary.exe)
- write the values in a text file (say that you name the file: salary.dat)
- launch the command: salary < salary.dat.

try also: salary < salary.dat > out.dat
and : salary < salary.dat >> out.dat

The above is redirection.

Better yet: if the values to be fed to salary.exe are the output of another 
executable (say it: compute.exe), assuming that it writes to stdout, you 
could tie the output of "compute" to the input of "salary" by the following 
command:
compute | salary

The above is an example of a "pipe".

Hope this was of some help.

Thanks to everyone who replied. I had expected the <cr> to be a legal input.
Thanks for the info.

No, it doesn't hang.
After the printf in the loop is executed, scanf still waiting legal input.

  while (scanf("%lf", &salary) == 1) {
     ...
  }

So to finish scanf, you have to give illegal input or non numeric
character, like 'x' (or another alphabet character you like) then press
[Enter].

Try to give input like this:

Enter salaries: 100 200 150 600 x [Enter]



If you write loop like this

  while (scanf("%lf", &salary) != EOF) {
     ...
  }

You can use <ctrl>Z to finish input.

[Dev-C++] Need some help with compiling PureLS (TCHAR probs ect..)

[Johannes P. <joh...@pr...>]

Hi All
-0-0-0-0

I need some help here with getting PureLS from : http://www.purels.net/

To Compile with DevC++ The problem is that for starters it uses TCHAR 
varaibles as _TCHAR
I geuss it is a Micro$oft thinf for I dont see it in the Header file of 
DevC++ So I added it ,, Saw No problem anymore
But I need to know that this define that I added wont effect DevC++ in 
other projects somewhere else ?? I hope not
and dont forsee it to, But I need to know. Also I have a problem that I 
cant get some help on _tfopen this is
a problem as I struggle to get the next piece of coding to compile

//-- SNIPPET START
         f = _tfopen(fPath, _T("r"));
//--END SNIPPET

I get the following Error

warning: assignment makes pointer from integer without a cast

This is funny And I cant seem to solve this for I cant give the function 's 
Address for my understanding says that it already
give a address back (the file pointer (stream pointer)). Thus I am missing 
something So please help in this sense..

Well that is all for now

Thanks for help

Johannes

Re: [Dev-C++] Basic C question: scanf

[Eric A. <eri...@ho...>]

Or you coul do
//Add the following lines
#include <ctype.h>

#define Done 0;
#define True !done;

While(!done)

then somewhere in the loop ask if they was to continue

printf("Would you like to enter more values? Y/N/x20");
ch=toupper(gets(ch));
If(ch == 'Y') Done = True;

then end the loop.

Re: [Dev-C++] Basic C question: scanf

[Vassili <v.v...@bt...>]

The reason it hangs, or seems to hang, is because your in a loop. The
scanf() is waiting for an input. When you type in an alpha character, the
return value isn't 1, so you exit the loop. You might be better off using a
"yes" or "no" style system to exit the loop. In essence, something like:

char ch = 'Y';   // Initialise to enter loop

while( (ch == 'Y') || (ch == 'y') ) {
  scanf();

  // Rest of code

  printf("Continue ?");
  ch = getchar();
}

Best of luck

Vas

Lo there
------------
Sorry but my mail does not always reach the mailing list. So I hope you 
forgive that I
am sending to your private mailbox also..

I have found a good starting point at some site's And they are as I found
in the following order helpFull..
NOTE one thing thou considering you want to write a 3D - game from scracth 
it would be nice that you know
some assembler also for when coming to graphics time is very important for 
you only have such a small gap to the
video memory to work with
But here is the sites as follows :

http://www.ddj.com/articles/2001/0165/0165f/0165f.htm

Is a programming black book for graphics. Is also from the oak who helped 
optimize Quake for 3d realtime

http://www.geocities.com/SiliconValley/2151/pcgpe.html

Is a old but goos site for info on how to start and what whent wrong known 
as PC Game Programming Encyclopedia.
Note look at the articles that was destiend for the second version. It can 
be helpfull
Also

http://www.qzx.com/pc-gpe/

And this is a online version of the above mentioned

http://qzx.com/lib/

Is a good libary with good links to sites with more info .. Use the search 
it is helpfull

Well good luck

No, it doesn't hang. 
After the printf in the loop is executed, scanf still waiting legal input. 

  while (scanf("%lf", &salary) == 1) {
     ...
  }

So to finish scanf, you have to give illegal input or non numeric
character, like 'x' (or another alphabet character you like) then press
[Enter].

Try to give input like this:

Enter salaries: 100 200 150 600 x [Enter]



If you write loop like this

  while (scanf("%lf", &salary) != EOF) {
     ...
  }

You can use <ctrl>Z to finish input.

[Dev-C++] Basic C question: scanf

[Mary S. <ms...@in...>]

I've written a short program using Dev-C++ 4, but it does not execute as I
would expect. The code is as follows:

#include <stdio.h>

int main(int argc, char *argv[])
{
  double salary, fed_withhold, state_withhold;
  double salary_sum = 0, fed_sum = 0, state_sum = 0;

  printf("Enter salaries: ");
  while (scanf("%lf", &salary) == 1){
        fed_withhold = salary * .17;
        state_withhold = salary * .03;
        printf("salary: %.2f fed tax: %.2f state tax: %.2f\n",
                        salary, fed_withhold, state_withhold);
        salary_sum += salary;
        fed_sum += fed_withhold;
        state_sum += state_withhold;
  }
  printf("\nSalary total: %.2f Fed tax total: %.2f State tax total: %.2f\n",
                   salary_sum, fed_sum, state_sum);

  system("PAUSE");
  return 0;
}

When the program is run, the prompt "Enter salaries:" is printed. After
that, I enter a series of numbers, then press the Enter key. The printf in
the loop is executed for each number input, but then the program hangs. I
have to either interrupt the program (<cntrl>-z worked for this) or type in
alpha characters and hit Enter. At that point the printf after the while
loop is executed.

What have I got wrong or what is it that I don't understand?

Thanks,

Mary

So, you want to make a 3d game
from the bottom... meaning you don't want to use OpenGL
or DirectX or suchlike?

Yep... I would like to code the entire thing my self. Straight from the
bottom :) What's the best way to do it, and how is good for games?

Oh, I can contribute here?  I am just starting to learn
C++, don't know much ;)  I've read what a raytracer is,
and could probly explain it to you, but it would be
better for you to read what I've read, so go to
povray.org.  While you're there, you may want to
download it, as povray is a free one.  I think the
difference between raycasters and raytracers may be the
difference between starting at the light source, and
starting at the camera, not sure.  I believe povray
uses both techniques, to get mirrors to reflect
properly, or something.  Somewhere on their site, they
say that raytracers are not very good for games yet, as
the raytracing process is horendously slow, and game
graphics are generally rendered in real-time.  So I
suggest you temporarily forget the idea of raytracing
for games, until computers do an even better job of
blowing our minds away.  So, you want to make a 3d game
from the bottom... meaning you don't want to use OpenGL
or DirectX or suchlike?

[Dev-C++] using alternate compilers?

[Jason O. <or...@am...>]

Is there any way to get Dev-C++ to use an alternate compiler executable =
name than gcc ?   for example the compiler executable name for the GCC =
tools for palmos is named m68k-palmos-gcc I've been able to use it by =
renaming it to gcc.exe but this seems a little kludgy.  Does anybody =
have any thoughts?

Hello !

I've just put online the new Dev-C++ Resource Site. This should be better 
than the one old page you used to see before. 
I hope to be able to put a lot of information, documentation and packages on 
it (it is currently still under construction) so this is why you can submit 
your own resource, and so participate to the evolution of this site.
You can reach it at http://www.bloodshed.net/dev or 
http://www.haikuzone.org/dev/

ps : i'll be out of town for about 4 days

Greetings !

When you use pushback() and vector is full, new objects within the
vector are created.

Code that works:

A)
#include <vector>

class A
{
};

int main()
{
vector<A> test(10);
A *p;
p=&test[0];
}


B)

#include <vector>

class A
{
};

int main()
{
vector<A> test(10);
vector<A>::iterator iter=test.begin();
A *p;
p=&(*iter);
}



Code that does not work (of course):

#include <vector>

class A
{
};

int main()
{
vector<A> test(10);
vector<A>::const_iterator iter=test.begin();
A *p;
p=&(*iter);
}



You probably were using const_iterator or doing something else wrong.

okay, that's pretty clear.  I had been looking at examples that start
with defining an empty container and then adding to it using pushback()
or insert(), so it wasn't clear to me...  I forgot that I probably have
to define copy constructors for my classes. Haven't tested this yet, but
this might be the problem...

nope, definitely defined as objects.
My problem is when I try to assign  &(*iter) to a pointer, I get compile
errors 
"initialization to `Book *' from `const Book *' discards qualifiers"
I'll make the new pointer a const, but that'll require another function
to be declared a CONST and on and on , to a point of uselessness.

[Dev-C++] button + win32

this code create a button with a bitmap over:

                  "OK",
                  WS_VISIBLE| WS_CHILD | BS_DEFPUSHBUTTON |BS_BITMAP,
                  5,
                  5,
                  46,
                  46,
                  hwnd,
                  NULL,
                  (HINSTANCE) GetWindowLong(hwnd, GWL_HINSTANCE),
                  NULL);

      hBitmap = LoadImage(0, "stud.bmp", IMAGE_BITMAP, 92, 44,
LR_DEFAULTCOLOR | LR_LOADFROMFILE);

SendMessage(hwndButton,BM_SETIMAGE,(WPARAM)IMAGE_BITMAP,(LPARAM)hBitmap);

now i have two problems:
    1. i want to move the position of the bitmap of few pixels.
    2. if i disabled the button with api "EnableWindow" the button become
gray, how can i avoid this?

i hope someone can help me.
