Thank you, I tried it over my complete files and works fine.
I use MinGW 2.0.0-2 separately from Dev, too.
In my code there was nothing more than that movement between files, I'll=20
try to rebuild it and see what happens now. I neither tried yet to enter=20
your test inside my project. I'll do it one of these couple days.
Thanks again.

Try getcwd():

  	  /#include/ /<unistd.h>/
	  /#include/ /<io.h> // <stdio.h> is standard but MinGW uses io.h/

	  /main()/
	  /{/
	       /char/ /*cwd;/
	       /if/ /((cwd/	/=/ /getcwd(NULL,/ /64))/ /==/ /NULL)/
	       /{/
		    /perror("pwd");/
		    /exit(2) <http://www.mcsr.olemiss.edu/cgi-bin/man-cgi?exit+2>;/
	       /}/
	       /(void)printf("%s\n",/ /cwd);/
	       /free(cwd);/
	       /return(0);/
	  /}/

The man page is at:
http://www.mcsr.olemiss.edu/cgi-bin/man-cgi?getcwd+3

Note that this is POSIX, Windows has their own non-portable API for 
directory and file operations.

Good luck!

I just downloaded Devcpp4, all the files: upgrade, devcpp4.exe,
devcpp401,devcpp4.src and installed all. You may want to check if this
software is compatible with your OS. I installed the Devcpp on my NT and
followed the same instruction from www.cprogramming.com today as a test
and it works.
You may have to reinstall again to make sure everything is done correctly.
 Let me know what the outcome is.

Subject: [Dev-C++] Dev C++ on Windows XP

Hi,

  I just downloaded and installed dev C++ for my windows XP machine. I
opened the hello project (hello world) and tried to compile it. But the
compiler is giving lots of errors saying that iostream.h is not available.
All the header files are there but the system is not able to recognize it.
Do I have to set some environment variables or something?? What do I need
to do? Your kind inputs in this regard would be appreciated.

End of Dev-cpp-users Digest

Balazs is correct.  However, there are a few other ways to do this.  For 
example, the C standard says that command line parameters will be passed 
into main as a count, and as an array of pointers to stings, just as 
Balazs said:

int main( int argc, char *argv[] ) {... }

argc is the ARGument Count, and argv is the ARGument Vector.  However, 
argv has one other little trick.  It actually has argc + 1 vectors, and 
the last vector is always NULL, so you can just ignore argc and count 
through the strings untill you find the NULL one, and that is the end. 
 Obviously, this wouldn't work if some of your strings in the middle 
have to be NULL, so watch out, but if they don't then it's a nice 
alternative to having to maintain a seperate count, although a little 
tricky to maintain.  See K&R section "Command Line Arguments" more info 
and nice pictures.

Also, you could have structure that has the count in the beginning and 
then a variable sized char* vector after it.  I believe gcc allows you 
to declare variable sized vectors like this:
struct string_vect{
 int count;
 char *string[0];
} string_vect;

Then you have just one variable to pass into functions instead of two. 
 Again the maintainace cost is a little higher (you have to remeber to 
allocate memory for this structure properly, i.e. malloc( sizeof (struct 
string_vect) + sizeof (char* [10])) for ten strings for example, but 
perhaps this would be better in the long run for you.

Good luck!
B.

P.S. I did NOT compile and check any of the code example given here. 
 Use at your own risk!

I tried a simple test program, it works fine with your input (FC returns no
differences). I'm running GCC 3.2. See if this program works with source.txt
being the above values.

----------- Start ------------
#include <iostream>
#include <fstream>

int main()
{
    using std::cout;
    using std::cerr;
    using std::endl;

    const int BUF_SIZE = 256;
    char buf[BUF_SIZE];

    std::ifstream in_file;
    std::ofstream out_file;

    in_file.open("source.txt");
    if(!in_file)
    {
        cerr << "Couldn't open source.txt\n";
        return 1;
    }
    out_file.open("dest.txt");

    while(!in_file.eof())
    {
        in_file.getline(buf, BUF_SIZE);
        out_file << buf << endl;
        cout << buf << endl;
    }

    return 0;
}

---------- Stop ------------

Tell me what you get. If you get the error (or even if you don't), try
upgrading to the latest MinGW with GCC 3.2. The URL I used is
http://osdn.dl.sourceforge.net/sourceforge/mingw/MinGW-2.0.0-2.exe.

It may be out-dated now. Check the MinGW website.

If I understand your problem corrrectly, you are unable to see the "Hello
world." message that is supposed to print out.  To rectify this, add
#include <stdlib.h> and in the line preceeding the return 0 command add
system("PAUSE");

Also, I do not understand why you #included windows.h.  There's no reason
to at all.

I believe strlen() would work in this case.  It counts the number of
characters in an array until it reaches the null terminator (which would be
the '\0' character, making yours redundant.)

Thanx for your help!

i just wanted to add that i need something for C not C++ ;), so i decided to 
end the arrays with "-1" and then check for it, that's only in case i have 
no "-1" in the array itself! and that's the case here

have a nice hard coding! :)

Khalid Al-kary

Hej all,
I would like to learn C and make win exe.
I'm using Win98 SE and DevC++ version 4 (not the newest).
The installed dir is C:\dev-C++ with Ming compile system (incl. in the
package)
My problem is I can not se whether the exe file runs or not.
There are no error message after compiling.
The c files are just a "Hello world" print out.
All the files are in 2 zip files, one for proj03 and the second for proj04.

The second question is the different between Ansi C and C and which is most
suitable with DevC++.

Thanks a lot

TriMy,

Hi, everybody.
I want to include printing in my application. I wanted to do this using
common dialogs (page setup dialog, print dialog), but when I saw that
gigantic DEVMODE structure, I gave up. Do I have to fill the entire
structure manualy, or I can use some default values? Is there a way to get
informations about printers from the system? I am also confused about
members of DEVNAME structure. I don't want to be anoying, but I hope someone
can give some general idea about using these dialogs and printing. Thanks.

I didn't try this, but maybe it could work:

#include <stdlib.h>

void main(void)
{
    test=3Dsystem("cd");
}
Since your main function is declared as void, it shouldn't return =
anything.
