Reading from a file into a linked list.

[Wiretron]

I've opened up the txt document using the fopen function, and am trying to get the program to 'read' the file.

I'm trying to get it to read the txt file 1 character at a time, but am not entirely sure how to do this, would I used

i = getchar();
while (i != EOF) { 
fscanf(fp,"%c",a); 
i++;
}

Whereby a and i are integers.

How would I the go on to store this information into a linked list?

Thanks in advance for any help.

use fgetc instead, it takes a file pointer, prototype is as follows:

int fgetc (FILE *fp);

i've never used this code myself, but i understand that it is suited to this type of situation. there's a tutorial on File I/O on this site, that's where i took this from, follow this link for more info on File I/O - there's also a link to an example using fgetc on the page

Thanks for that, I've got it reading the txt file character by character.

How would I then go about storing this into a linked list?

I want to store it word by word.

If possible could someone link me to a useful tutorial that is relelvant to this?

Thanks

i'm not familiar with linked lists, but my guess is that since you are reading in character by character, you should be able to create a new node on your list when you detect the ASCII space character (decimal 32). once you detect this, you read the next character into a new node untill you detect another space, and so on.

maybe someone else would be able to assist you in creating linked lists, i've never used them myself, but i'm guessing that you might be familiar with them yourself already. hope that this helps a little at least.

Ok thanks for your help, I understand the concept of what you're saying, just gotta work out how to do linked lists, and how to create a new node when a space is detected etc!

If anyone has a useful tutorial or some advice, please post!

int ch;
while ( (ch=fgetc(fp)) != EOF ) {
  // do something with ch
}

As for linked lists, there's plenty of examples to look at if you do a board search.
