Thread: Help with an error message

Hi
I have a trouble with an error message that appear for my code
The message is:

In function ‘reverse’:
myfile.c:34: warning: large fixed-point constant implicitly truncated to fixed-point type
myfile.c:34: error: fixed-point types not supported for this target

the only i'm trying to do is:

Code:

{       
        int p,y;
	int r=0;
	x=(x<0)?-x:x;
	while (p>=0)
	{
		y = x % 10;
		p = x/10;
		r = 10r + y;   //THIS IS THE LINE 34!
		x = p;
		printf("%d",r);
	}
	return 0;
}

I didn't even know "10r" was valid C. I imagine you meant "10*r".

Are you trying to multiply by 10? If so then it should be
r = 10 * r + y;

oops yea!
ohh my godness! I didnt notice that! bfffff
I;m really sorry! I feel like an idiot

bfff can u please help me for another thing? :/

Your current directory may not be in your path (it often isn't in unix-y systems). You would then have to type "./myprogramme". (This assumes that you have successfully compiled your program, and it isn't called "a.out".)

And its also on the same path!I have checked it with "ls" command

ls doesn't check your path, it just tells you what files are in your current/specified directory. You can check your path with something like "$PATH".

with "$PATH" i get this one:

"$PATH".
bash: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games.: No such file or directory

maybe i understood wrong.

The period was just the end of the sentence. But the bottom is the path: those seven directories are where the system will look for an executable file. None of them is your current directory, so to execute your program you will need to give the full (-ish) path. So type

Code:

./myprogramme < myfile.txt

so your system knows what directory to look in.

ok i fixed it! Thanx!

EDIT:
what does this warning mean?

gcc -o reverse reverse.c
/usr/lib/gcc/x86_64-linux-gnu/4.4.1/../../../../lib/crt1.o: In function `_start':
/build/buildd/eglibc-2.10.1/csu/../sysdeps/x86_64/elf/start.S:109: undefined reference to `main'
collect2: ld returned 1 exit status

Thanx in advance,and sorry for the many questions!

That means you need to have a function called "main" in your program, because that's the function that is automatically called by the system when you run your program.
