Sounds like you're forgetting the <NL> at the end of an input line.
Thus, the second time through the loop, the <NL> will be the first
character of input.  To get around this problem, do an extra getc after
you do the fscanf to eliminate the <NL>.  Then it should work properly.
For the fscanf, "%c%c%s" should do as format effectors.
