only works for second function call

xylon89del1 — Sat, 06 Sep 2008 18:35:06 +0800

here is my code:
++++++++++++++++++++++++++++++++++++++++++++++++++++++
#include<stdio.h>
#include<string.h>

void f1(char *a){char c;int i=0;
while((c=getchar())!='\n')
a[i++]=c;
a[i]='\0';}

int main(){
int path2=1;
char newword[20];
char newnoun[50];
char newadjective[50];
char newverb[50];int choice;
FILE *fptr;
printf("Enter your choice");
scanf("%d",&choice);
if(choice==1){printf("it is one.");}
else if (choice==2){
if((fptr=fopen("list1.dat","a"))==NULL){printf("The file cannot be opened.\n");}
else while(path2!=0){
void f1(char *a);
printf("Word:");
f1(newword);

printf("Definition(noun):");
f1(newnoun);

printf("Definition(adjective):");
f1(newadjective);

printf("Definition(verb):");
f1(newverb);

fprintf(fptr,"\n%s %s %s %s",newword,newnoun,newadjective,newverb);
printf("Enter 1 to continue ,enter 0 to go to quit.");
scanf("%d",&path2);}
fclose(fptr);}

return 0;
}
+++++++++++++++++++++++++++++++++++++++++++++++++++++++

here is my output:
++++++++++++++++++
Enter your choice2
Word:Definition(noun):
+++++++++++++++++++++

from the code, after "the word:",i suppose user is given a chance to input data.
but, it skipped through...it only works for the second function call...

anyone please shade me the light.

i found out the reason ady, this is due to the scanf();
in case someone can know,
i just make a workaround by adding the the following code
after the scanf();

if((s=getchar())!='\n'){printf("I catch a new line.");}

it works as to eat up the '\n'

but, i think this is just a small trick.
hope the pros can shade me new light if there is a better solution ...

incompatible type in assignment

xylon89del1 — Sat, 06 Sep 2008 01:30:46 +0800

i keep on getting the error saying that incompatible type in assignment in the following code:

///////////////////////////////////////////
#include<stdio.h>
struct op{char similar[30];};

int main()
{

struct op option[20];
option[0].similar="hello world";
printf("%s",option[0].similar);

return 0;}
///////////////////////////////////////////
but, i cant really debug out what is wrong with my code..
someone please shade me the light..

QUOTE(xylon89del1 @ Sep 6 2008, 01:30 AM)

i have found the answer..
in case anyone would like to know the solution,
struct op{char similar[30];};
must change to struct op{char *similar}
coz array is not lvalue, therefore it cannot be on the left side in an assignment..
correct me if i am wrong./

gets is dangerous

xylon89del1 — Fri, 05 Sep 2008 22:27:42 +0800

i am writing a c program

i have come across that gets() function is quite useful to get the string from standard input...
however, when i use it in my code, and when the time i compile it,
it prompts out that gets is dangerous...
anyone know the reason for tat?

is there any other function out there which has a more or less similar function as gets()?

error:file is a binary type...

xylon89del1 — Fri, 05 Sep 2008 16:06:31 +0800

fluendo mp3 decoder

xylon89del1 — Sat, 12 Jul 2008 21:39:50 +0800

i wanna install the fluendo mp3 decoder.
but, after i download it, the content inside are not as complete as listed in the readme.
the readme is as followed:
====================================
Please copy all the files contained in the codecs directory in
the following directory ~/.gstreamer-0.10/plugins/

As a commodity you can run the following command line from a terminal :

user@host$ mkdir -p ~/.gstreamer-0.10/plugins; cp ./codecs/* ~/.gstreamer-0.10/plugins/

Once this is done a simple :

user@host$ ls ~/.gstreamer-0.10/plugins/

should show the following list of files (or only some of them if you did not
buy the complete codec pack):

libgstfluac3dec.so libgstflumcaacadec.so libgstflumpeg4videodec.so
libgstfluasfdemux.so libgstflumms.so libgstflumpegdemux.so
libgstfluh264dec.so libgstflump3dec.so libgstfluwmadec.so
libgstfluisodemux.so libgstflumpeg2vdec.so libgstfluwmvdec.so
============================================================
inside my codec directory , there is only libgstflump3dec.so

however, i try to to install it.
but, the amarok still cannot read mp3 file

so, is there any other free mp3 decoder that i can download?
or i already download the right thing and i just need that file.
the only prob tat i cant read the mp3 file is i install it wrongly????

compiling problem

xylon89del1 — Sat, 12 Jul 2008 11:55:01 +0800

i am compiling a printer driver source code here.
in the process, when i type the command 'make gen"
here is some notification i get in the terminal.
==============================================================
Please add the files
codeset.m4 gettext.m4 glibc21.m4 iconv.m4 isc-posix.m4 lcmessage.m4
progtest.m4
from the /aclocal directory to your autoconf macro directory
or directly to your aclocal.m4 file.
You will also need config.guess and config.sub, which you can get from
ftp://ftp.gnu.org/pub/gnu/config/.
===================================================================
there r two methods to add the files .
the first one is to add into the autoconf macro directory.
my prob is that how can i noe which directory is the macro directory.there is no specific file that match the autoconf macro exactly.
the second method is to add those files into the aclocal.m4 file.
and here how can i copy a file to a file?
