Actually your original solution is the better one. If fread fails for reasons other than eof, it will not go to an infinite loop

Haha, my post seems totally pointless now. I am going to update it and give you the credit for a much better solution

Yep. I already had troubles with “feof()”. The key thing to remember is that you must use the while as if you were looping with an integer as the iterator like:

int i = 0;
while ( i < 9 ) {
printf(“%d”, i);
i = i + 1;
}

The difference is that you are iterating in a file stream:

unsigned char byte;
fread(&byte, 1, 1, fp);
while ( !feof(fp) ) {
printf(“%c”, byte);
fread(&byte, 1, 1, fp);
}

But, if you compare the two algorithms, you will see the same pattern.
