[<or...@vp...>]

Hi!

Hehe.
What is this, some common type of homework or book excersise? :)
Some time ago, someone asked *exactly* this question, and at least 2 
solutions were supplied. However, the subject of the letter doesn't 
indicate the question, so no wonder you haven't found it.

Anyway, look here:
http://sourceforge.net/mailarchive/message.php?msg_id=6318449
for my solution, but there are others as well.

[Timo D. <tim...@we...>]

Hello

This is my first post :)
I hope someone could help...

I want to use DevCpp for a .c source with an external makefile and externa=
l headers and libraries. Furthermore, I don't want to build a .exe but a .=
mi file. That binary is supposed to run on a digital signal processor and =
not on a pc.

Up to now, I successfully used Cygwin to build this special .mi. So I have=
 that makefile to do this. The makefile calls "tmcc.exe" which is a specia=
l compiler for trimedia devices.=20

I installed DevCpp 4.9.8.0, created a new empty project and added (project=
->project options->makefile ) my external makefile to the project. I tried=
 to compile the source and got a error :

/////////////////////////////////////////////////////////////////////

The FOX library name is usually spelled "libFOX.*", with uppercase  
letters for the "FOX" part. The link line that you showed appears to be  
looking for a "libfox.*", where the "FOX" part is spelled with  
lowercase letters.

You probably need to check the list of libraries linked into your  
application (however that is done in Dev-C++) and change the spelling  
of that library from "fox" to "FOX".

Yes, if you call gcc with the -S option you'll see that _every_ global
var, unless differently specified, is initialized with the 0 value, but
this is true for GCC and not for all compilers.

No, the stack is never cleared (push and pop don't delete data, just
declare it useless) so on its top there are datas of the other functions
you invoked, or random data; but vectors are used from top to bottom, so
that loop won't print that, but all internal vars previously allocated,
the function (main) arguments, and so on until some of this is 0 or is
reached the end of the segment (that results in a segmentation fault on
Unix and an access violation in Windows)..

main is a function like others; simply some compilers can decide to
inizialize vars pushing zeros instead of allocating blank spaces. I can't
believe compilers can allocate as globals main internal vars.

[Dev-C++] Reversing a string word by word - advice on my code please

[Daniel G. <sp...@ho...>]

Hi all,
I'd appreciate some code review on the logic of this function I wrote.
I'm using C# (does Dev support C# ?) (with the csc.exe compiler) to reverse 
a string and after a bit of struggling (though an idiotic mistake on my part 
- it is really embarassing) I managed it, and would like you to have a look 
at the code and tell me if there is a better way of doing it.

The logic is in question here, so don't worry about not knowing C#. 
StringManip is my class which has one 'string' member we are interested in, 
mCompanyName, which is being reversed.

/* ReverseSentenceByWord() is a function that reverses individual words in a 
string. It does this
           by looking for spaces and reverses all the letters before that 
space.
        */
        public void ReverseSentenceByWord(ref StringManip SentenceObj)
        {
            string Sentence = SentenceObj.mCompanyName;

            // This number increases each time the iterator moves forward, 
counting the length of the word.
            int CharsInWord = 0;
            // StartOfWord is a marker for where the start of the word 
begins. For example the first word will
            // always start at 0 (first element), but the next word may 
start 7 characters in (6).
            // This is required to reverse only one word at a time.
            int StartOfWord = 0;
            int EndOfWord = 0;
            int Iterator = 0;

            // What is the total length of the sentence?
            int TotalChars = Sentence.Length;

            // While we are not at the end of the string continue to run the 
code inside
            while(Iterator != TotalChars)
            {
                // If this is the second time around then the start of the 
word variable needs to change
                // (otherwise we'd be counting from the first letter every 
time).
                StartOfWord = Iterator;
                // Same for the number of characters in the word.
                CharsInWord = 0;

                // Count how many characters there are from the current 
iterator position to the next space.
                // But be sure to guard against indexing the end of the 
array.

                while(Sentence[Iterator] != ' ')
                {
                    if (Iterator == TotalChars-1)
                    {
                        // We are on the last letter so to catch it we must 
increase CharsInWord.
                        CharsInWord += 1;
                        break;
                    }
                    // Look at the next character
                    Iterator += 1;
                    CharsInWord += 1;
                }


                // In the case of a double space the character before will 
be ' ' so guard against this first of all
                // by saying "if the previous char is a space then loop 
again".

                {

iterator's position minus one (we are sitting on a space
                    // at the moment). We still have the starting position 
stored from the previous loop (or 0 if this is the first time).
                    EndOfWord = Iterator - 1;

                    // Perform a quick check to ensure that the CharsInWord 
variable is correct.
                    if (CharsInWord == (EndOfWord - StartOfWord))
                    {
                        Console.WriteLine("\n\nNumbers do not match\nThe

the end of the word (using CharsInWord counter).

<snip>

In FOX 1.0, the class name for the menu bar widget is FXMenubar (note 
the lowercase "b"). In FOX 1.1 (i.e. the fox-1.1.x development series) 
it has been renamed to FXMenuBar (with an uppercase "B"). Are the FOX 
header files that you're compiling against those from FOX 1.0 or FOX 
1.1? If it's the former, you need the latter ;) And of course, you will 
need to link your executable against the corresponding version of the 
FOX library; if you're compiling against the fox-1.1.42 header files, 
be sure to link against the fox-1.1.42 version of the library.

Note that the fox-1.1.x series is the unstable development version; it 
is quite possible that there will be API changes between whichever 
fox-1.1.x you're using and subsequent versions in that series. If 
you're looking for a stable FOX release to develop against, for now 
that version is FOX 1.0.

Hope this helps,

Lyle

I think what you have demonstrated is that in order to compile FLTK
programs, you want to link against the FLTK libraries.

EDITTEXT doesn't have a string before the identifier.

Well, to me it seems that the explanation is that GCC stores the variable=
s
declared in main on the stack! If you put the declaration of the v vector
outside main, the program will "work" just as with the other compilers. T=
his
probably is because windoze will clear the memory (setting to zero) alloc=
ated to
the program before loading and executing it. The memory occupied by the s=
tack is
cleared just like all the rest, only it is messed up by some initializati=
on code
executed before main starts executing.

If you put the same code in some other function than main it won't work (=
except
by chance) regardless of which compiler you use.


A way to verify this behavior is to put "int v[3000000]" outside of main =
and
inside. And yes, the program crashes if you put the declaration inside ma=
in,
because windows don't allow you to allocate that much (at once) on the st=
ack. My
guess is that the other compilers treat declarations inside main as if th=
ey were
put outside of main (go ahead and try).=20

Note that the clearing of memory before loading and executing the program=
 is not
 part of the C/C++ standards but is dependent on the OS. Visal C++ (when
debugging) even initialize memory to 0xaa (or was it 0x55?) to help detec=
ting
this kind of bugs.=20

[Dev-C++] unspecified? Why?

[Mohamed I. <mi...@ac...>]

 26.2/2: The effect of instantiating the template complex for any type other
than float, double or long double is unspecified.

Does anybody know the reason for that?

[Dev-C++] '0' is not recognized as an internal or external command,

[Stas <sr...@um...>]

I just installed Dev-C++ into the default directory. I opened up the =
sample console project and I attempted to compile it. I got this error.

Compiler: Default compiler
Building Makefile: "C:\Dev-Cpp\Testing\Makefile.win"
Executing  make...
make.exe -f "C:\Dev-Cpp\Testing\Makefile.win" all
g++.exe main.o  -o "Project1.exe" -L"C:/Dev-Cpp/lib"=20

'0' is not recognized as an internal or external command,
operable program or batch file.

make.exe: *** [Project1.exe] Error 1

Execution terminated

It's obviously not a programming problem but I'm not really sure what =
config files to change or where to start looking for a fix to this =
problem. I've reinstalled Dev-C++ twice now hoping that maybe it was a =
non-defualt directory type error but still no luck.
