RE: [Dev-C++] Fibonacci numbers / unsigned long long int

[<Mat...@Ve...>]

Try the option -std=c99 as one of your GCC options. The long long integer
type only works right in C99 C code. Let me know how it turns out.

Subject: [Dev-C++] Fibonacci numbers / unsigned long long int


Hello

The following code, when assembled by dev-cpp calculates the incorrect 49th
Fibonacci number, which should be 4807526976. However, when compiled by
another assembler (lc.exe), it works fine.

The 47th Fibonacci (1836311903) and 48th Fibonacci (2971215073) are 
calculated correctly, but when they're added together to create the 49th 
Fibonacci, the answer is incorrectly calculated and displayed.

Does Dev-C have to be configured in any special way to handle unsigned 
long long integers?
 
/* Generate Fibonacci numbers using variable length arrays  */
 
#include <stdio.h>
 
int main (void)
{
    int i, numFibs;
 
    printf ("How many Fibonacci numbers do you want (between 1 and 75)?");
    scanf ("%i", &numFibs);
 
    if ( numFibs < 1 || numFibs > 75 ) {
       printf ("\nNumber must be between 1 and 75!!\n");
       return (1);
    }
 
    unsigned long long int Fibonacci[numFibs];
 
    Fibonacci[0] = 0;  // by definition
    Fibonacci[1] = 1;  // by definition
 
    for ( i = 2; i < numFibs; ++i )
        Fibonacci[i] = Fibonacci[i-2] + Fibonacci[i-1];
 
    for ( i = 0; i < numFibs; ++i )
        printf ("%llu\n", Fibonacci[i]);
 
    printf ("\n");
 
    return (0);
}

[Dion B. <dio...@in...>]

Thanks Per

Yup, the "%I64u" change did the trick!! My program works fine now when 
compiled with Dev-C.

Fibonacci number do grow very quickly, and so it would seem that the 
32bit length was being exceeded upon creating the 49th Fibonacci.

Once again, thanks for all the helpful support.

Re: [Dev-C++] Fibonacci numbers / unsigned long long int

[Dion B. <dio...@in...>]

Thank you for the program you sent Puime, but I've already coded=20
something similar, and yes, this approach works equally well.

However, generating Fibonacci numbers is not what this is all about.=20
This is about unsigned long long int used in arrays and the fact that=20
compiler x doesn't work but compiler y does.

Why the difference?

Is it a compiler issue or is it a Dev-C issue? My thought on the matter=20
is that it's Dev-C issue, but I'm not sure, which is why I raised the=20
question.

Can anyone else please provide some extra input?

Re: [Dev-C++] Fibonacci numbers / unsigned long long int

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

Nothing wrong with the long long int declaration.

However, MinGW is using Microsoft libraries, and the Microsoft libraries
doesn't understand the "%llu" formatting parameter. Instead, "%I64u" must
be used to print 64-bit numbers. Since the x86 architecture stores lowest
byte first, "%llu" becomes "%lu" and the least significant 4 bytes gets
printed and the most significant 4 bytes are left on the stack for
following printf parameter declarations to use...

It appears you may be exceeding the length of a 32 bit int, which is what probably happened with the long long int declaration.  Try declaring long long instead of long long int for Fibonacci.  Interesting bug!

Re: [Dev-C++] custom GUI

I haven't looked at wx-devcpp, but if you haven't done any GUI programming
using any other tools, I definitely recommend having a look at wxWidgets.
Besides being portable between a large number of platforms (Win32, Mac,
OS2, Linux, ...) there are a lot of sample code showing off all parts of
the framework - how to display menues, input dialogs, draw graphics, ...

Hi,

I just started using wx-devcpp 4.9.9.1-wx-beta-6.6, which is
down-loadable at downloadable at: http://wxdsgn.sourceforge.net/ and is
a morph of Dev-Cpp.  Actually it's pretty good, as it has some features
not implemented in the standard 4.9.9.1 build.  I haven't tried 4.9.9.2
yet so I can't tell if the same tools are present.

It's fully integrated development environment (IDE) for wxWidgets. 
There's also Fluid for use with FLTK, and other GUI IDE's out there. 
Try googling for GUI IDE and see what you come up with.

There are no include file called "cstdio.h"

In older c++, the file was called "stdlib.h" and was actually part of the
C standard. In the current C++ standard, the file is called "cstdlib",
i.e. no ".h" extension. If you look at the answer you got before, it shows
<cstdlib>, i.e. your like should look like:

Re: [Dev-C++] opening files in c

[daniel <mag...@nt...>]

Thnaks for the help. I tried using the execute statement but it cam up with
the following error:

"/Programming/c_programming/c/practical_c/file_execute.c
D:\Programming\c_programming\c\practical_c\D cstdlib.h: No such file or
directory."

It seems as if its looking for the header file in the same directory as the
source file. Why does it only do this with <cstdlib.h> and not <stdlib.h> or
indeed <stdio.h>

Hello everyone,

I've solved the problem; I actually had a     wincl.lpszMenuName =
NULL; line just after I defined my menu... stupid me ;)

[Dev-C++] No Menu

[Karim Liman-T. <klt...@gm...>]

Hello,

I've recently installed Dev-C++ v 4.9.9.0 (5 beta) and I'm trying to
define a menu. I have browsed the mailing list archive and have found
a similar problem but it didn't help me solve mine. Here are my source
codes:

====================== main.cpp ===========================

#include <windows.h>
#include "resource.h"

/*  Declare Windows procedure  */
LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM);

/*  Make the class name into a global variable  */
char szClassName[ ] = "HelpClientClass";

int WINAPI WinMain (HINSTANCE hThisInstance,
                    HINSTANCE hPrevInstance,
                    LPSTR lpszArgument,
                    int nFunsterStil)

{
    HWND hwnd;               /* This is the handle for our window */
    MSG messages;            /* Here messages to the application are saved */
    WNDCLASSEX wincl;        /* Data structure for the windowclass */

    /* The Window structure */
    wincl.hInstance = hThisInstance;
    wincl.lpszClassName = szClassName;
    wincl.lpfnWndProc = WindowProcedure;      /* This function is
called by windows */
    wincl.style = CS_DBLCLKS;                 /* Catch double-clicks */
    wincl.cbSize = sizeof (WNDCLASSEX);
    wincl.lpszMenuName  = MAKEINTRESOURCE(IDR_MENU); /* Menu attached
to window /*

    /* Use default icon and mouse-pointer */
    wincl.hIcon = LoadIcon (NULL, IDI_APPLICATION);
    wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION);
    wincl.hCursor = LoadCursor (NULL, IDC_ARROW);
    wincl.lpszMenuName = NULL;                 /* No menu */
    wincl.cbClsExtra = 0;                      /* No extra bytes after
the window class */
    wincl.cbWndExtra = 0;                      /* structure or the
window instance */
    /* Use Windows's default color as the background of the window */
    wincl.hbrBackground = (HBRUSH) COLOR_BACKGROUND;

    /* Register the window class, and if it fails quit the program */
    if (!RegisterClassEx (&wincl))
        return 0;

    /* The class is registered, let's create the program*/
    hwnd = CreateWindowEx (
           0,                   /* Extended possibilites for variation */
           szClassName,         /* Classname */
           "Windows Help",       /* Title Text */
           WS_OVERLAPPEDWINDOW, /* default window */
           CW_USEDEFAULT,       /* Windows decides the position */
           CW_USEDEFAULT,       /* where the window ends up on the screen */
           544,                 /* The programs width */
           375,                 /* and height in pixels */
           HWND_DESKTOP,        /* The window is a child-window to desktop */
           NULL,                /* No menu */
           hThisInstance,       /* Program Instance handler */
           NULL                 /* No Window Creation data */
           );

    /* Make the window visible on the screen */
    ShowWindow (hwnd, nFunsterStil);

    /* Run the message loop. It will run until GetMessage() returns 0 */
    while (GetMessage (&messages, NULL, 0, 0))
    {
        /* Translate virtual-key messages into character messages */
        TranslateMessage(&messages);
        /* Send message to WindowProcedure */
        DispatchMessage(&messages);
    }

    /* The program return-value is 0 - The value that PostQuitMessage() gave */
    return messages.wParam;
}


/*  This function is called by the Windows function DispatchMessage()  */

LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT message, WPARAM
wParam, LPARAM lParam)
{
    switch (message)                  /* handle the messages */
    {
        case WM_DESTROY:
            PostQuitMessage (0);       /* send a WM_QUIT to the message queue */
            break;
        default:                      /* for messages that we don't deal with */
            return DefWindowProc (hwnd, message, wParam, lParam);
    }

    return 0;
}

===========================================================

Here's my resource header file:

==================== resource.h ===============================

#define IDR_MENU                        101
#define ID_FILE_OPEN                    102
#define ID_FILE_PRINT                   103
#define ID_FILE_EXIT                    104
#define ID_EDIT_COPY                    105
#define ID_EDIT_ANNOTATE                106
#define ID_BKMARK_DEFINE                107
#define ID_OPTION_ALWAYSONTOP_DEFAULT   108
#define ID_OPTION_ALWAYSONTOP_ENABLED   109
#define ID_OPTION_ALWAYSONTOP_DISABLED  110
#define ID_OPTION_SHOWHISTORY           111
#define ID_OPTION_FONTSIZE_SMALL        112
#define ID_OPTION_FONTSIZE_MEDIUM       113
#define ID_OPTION_FONTSIZE_LARGE        114
#define ID_OPTION_USESYSCOLORS          115

===========================================================

And finally the resource file itself:

===================== resource.rc =============================
#include "resource.h"

IDR_MENU MENU
BEGIN
    POPUP "&File"
    BEGIN
        MENUITEM "&Open", ID_FILE_OPEN
        MENUITEM SEPARATOR
        MENUITEM "&Print", ID_FILE_PRINT
        MENUITEM SEPARATOR
        MENUITEM "E&xit", ID_FILE_EXIT
    END
    
    POPUP "&Edit"
    BEGIN
       MENUITEM "&Copy", ID_EDIT_COPY
       MENUITEM SEPARATOR
       MENUITEM "&Annotate", ID_EDIT_ANNOTATE
    END
    
    POPUP "&Bookmark"
    BEGIN
        MENUITEM "&Define", ID_BKMARK_DEFINE
    END
    
    POPUP "&Options"
    BEGIN
        POPUP "&Always on top"
        BEGIN
                MENUITEM "&Default", ID_OPTION_ALWAYSONTOP_DEFAULT, CHECKED
                MENUITEM "&Enabled", ID_OPTION_ALWAYSONTOP_ENABLED
                MENUITEM "D&isabled", ID_OPTION_ALWAYSONTOP_DISABLED
        END
        
        MENUITEM "&Show History...", ID_OPTION_SHOWHISTORY
        
        POPUP "&Font Size"
        BEGIN
                MENUITEM "&Small", ID_OPTION_FONTSIZE_SMALL
                MENUITEM "&Medium", ID_OPTION_FONTSIZE_MEDIUM, CHECKED
                MENUITEM "&Large", ID_OPTION_FONTSIZE_LARGE
        END
        
        MENUITEM "&Use system colors", ID_OPTION_USESYSCOLORS
    END
END

===========================================================

There's no error on compilation but the resulting .exe is menu-less.

I'd be very grateful if someone could help me.

RE: [Dev-C++] opening files in c

[<Mat...@Ve...>]

OK,

Your terms are mixed up. In C/C++, opening a file means getting it ready to
be read and/or written from/into by your code.

Open does _not_ mean to execute a file. For executing a file, you need
system() which is in <cstdlib>.

Subject: [Dev-C++] opening files in c


Hello,
        I am writing a program which asks the user whether they want to
execute (open) a batch file or not. 
I tried using the fopen function but it seems to only enable you to write to
a file or read from a file (e.g. calculate the number of words in a given
file). 
What I want to do is open an external file. Is there a command for this?

 well, if you are doing a console application one thing you could try =
would be:
=20
system(" path\to\the\batchfile.bat");
=20
anything beyond that I would not be able to tell you about.
