Faulty while loop

[bildad]

Why does my while loop print the last line of the file twice?
Thanks.

void ReadFile(FILE *fp)
{
char buff[MAX_LEN];

while (!feof(fp)) {
fgets(buff, MAX_LEN, fp);
printf("%s", buff);
}
}

Never mind. I should have read posts before sending. Sorry.

Because you're using feof() to check for an end-of-file condition at
the top of the loop. Using the return value of fgets() instead, or
(i believe) checking at the end of the loop, would both solve your
problem.
