Hello. I was wondering how to read strings from a file word by word and store the words into an array in c. I am having to write a program that tests words to see of they are palindromes from a little paragraph i wrote in a file. I've been trying to figure it out all afternoon with no luck.:(

#include <stdio.h> main() { FILE *fp; fp = fopen("test.txt", "w"); fscanf(fp, "%s", buffer); printf("Read Buffer: %s\n", %buffer ); flcose(fp;); }To better understand fscanf try viewing :

I hate to sound like a prick but... using fscanf is generally a bad idea. There are plenty of reasons, but a big one is that most people don't really understand what its doing. Therefore it usually only works with carefully formatted input. Or by accident.

I have looked at strtok but I didnt think that it would work with data i am reading in. All the examples i seen were declaring the array as a certain string like
char array1=" your string here"
and then using strtok. I didn't really understand how to use strtok.
