In Topic: Writing different node to different files

Posted 27 May 2012

I am already trying to do it like this

void writeFileToNode(char *klas,int lng)
{
    char *file_any;
    FILE *infile=fopen(klas,"r");
    if (infile==NULL)
    {
        printf("File %s tidak ditemukan",klas);
        getch();
    }
    else
    {
        fgets(file_any,99,infile);
        klas[(strlen(klas)-4)] = '\0';
        insertKelas(klas,lng);
        while(strtok(file_any,",")!=NULL)
        {
            printf("%s",file_any);
        }

But why it can't input to my program?

Hello... Now I touching this project again. How I can read all files to just one variables in fgets and how I limit my string length in fgets? It will read whole character in file right?

And anyway, I remember someone told me to not using fflush(stdin) because it will makes undefined behaviour. But how I can remove buffer from my input if not using this? Because in my program if I try to stop my buffer with getchar() it works for sometimes like if I just input my data once. If I input it twice getchar() won't work and it will vanishing my 1st char.

I hope somebody still remember this thread

Ok, now I can fixed my input. Thanks a lot.
Anyway I still can't read from file to my program. This is my file look alike.

albi,1150,2011,3.28
arik,1050,2010,2.50

And this is my code :

void writeFileToNode(char *klas)
{
    char nama[31],nim[16];
    int angkatan;
    float ipk;
    FILE *infile=fopen(klas,"r");
    if (infile==NULL)
    {
        printf("File %s tidak ditemukan",klas);
        getch();
    }
    else
    {
        klas[(strlen(klas)-4)] = '\0';
        insertKelas(klas);
        kelas *itr=head;
        //this is my looping
        for(int i=0;i<40;i++)
            //this is how I input it to my program
            fscanf(infile,"%30s,%15s,%d,%f\n",itr->siswa[i].nama,itr->siswa[i].nim,&itr->siswa[i].angkatan,&itr->siswa[i].ipk);
        fclose(infile);
        printf("Anda telah berhasil mengimport\n");
        getch();
    }
}

Can anybody help me?

How about fgets (like jimplumberg suggested) and then finding the newline in the string and replacing it with NUL-character ('\0').

Ok, I will try it.

One solution is the following:
```
while(getchar()!='\n')
	continue;
```
Using getchar()? Doesn't getchar just saving a character? How it can be used to save string?

So what should I do to discard \n from my input? Am I need to make own function? Isn't that slowing my program?
