problem using strtok and fscanf together

ok, im doing this program and i want the program to read from a file characters that are separated by periods, but i do not want the periods to be read in, so basically what i do is i read the string from a file, and then i use strtok and copy the tokens to another file. However, it only works for the first one, after that, fscanf wont read the next string, it returns -1. this happens only after it does the tokenization. My code can be located at this here:

Why don't you just use

Code:

while ( fgets( buff, sizeof buff, fp ) != NULL )

and squash several bugs in one go.

ok i will do that, but can you tell me why fscanf wont work after i use strtok

It will - it's just you're probably
- not understanding how fscanf works
- you're losing white-space with %s
- you use a lot of strcpy, where I think you meant strcat
- you're probably overflowing some buffers.

well i checked on this website, it said it shouldnt work because strtok is not reentrant if youre using it in a loop. So i think im going to change it. Here's the site if you wanna read what they wrote.
