Thread: Question about File Input

The two loops would be identical except the first wouldn't save the line and the second would:

Code:

int n;
char buf[81];
char (*lines)[81];

/* fopen fin and such */
n = 0;
while ( fgets ( buf, sizeof buf, fin ) != NULL ) {
  n++;
}
lines = malloc ( n * sizeof *lines );
rewind ( fin );
n = 0;
while ( fgets ( buf, sizeof buf, fin ) != NULL ) {
  strcpy ( lines[n++], buf );
}
