Windows isn't liking this, neither is dos

I got this code from gametutorials.com, I had to modify it for my complier (its tutorial about file reading #2), sometimes windows will read it, but it will give invalid assignemnt errors most of the time.

Code:

#include <iostream.h> 
#include <string.h> 
#include <fstream.h>

int main()
{
	ifstream file_in("GT.txt");

		if(!file_in)
			return 1; 

	char a_word[10];

	while(!file_in.eof())
	{
		file_in >> a_word; // Here we read in a "word"

		if (strcmp(a_word,"\n")==0)
		cout << "\n";

		else
		cout << a_word; 

		cout << " "; 
	}

	file_in.close();

	return 0;
}

GT.txt :

Testing line 2.

Check it out, it's in the FAQ

k, it doesn't like this way either:

Code:

while(strcmp(a_word,"<10>")!=0)

note: i ended the gt.txt with a <10>, and I only changed the while, it gives the same error

Edit> editing the text file, I managed to get the program to work, however, it repeats the contents of the file twice, and it doesn't accept periods in the file.

Edit2> k, I got it working
