When ran it outputs the correct information but it also includes the line Invalid input. Type 'rec' following by the name or 'stop' if done. for a reason that i don't understand. The program also acts strangely after you put lets say fire instead of rec fire, after you enter fire it is supposed to say "Invalid input. Type 'rec' following by the name or 'stop' if done." and then you put in rec fire, however it won't accept anything as an input. and lastly i need it to output how many rectangles there are but i don't know which variable that corresponds to.
ANY HELP would be much appreciated!!
