# Hi - This is Charles, and I'm going to write just a tiny bit of code.
# I hope it'll clear things up for you. 
# I think you're getting tripped up on stuff you've learned before - 
# please try to approach this stuff with an open mind. It requires
# patience, but you'll eventually get the hang of it, I promise. 
# These early steps are supposed to be hard! Patience now will 
# pay off tenfold in a few weeks. 

# I see you doing things that you must have seen in other languages!
# That's cool, but please be patient and really
# try to learn things here from the ground up. 
# The best place to do that is to read the course material!


# This might be more confusing, but bear with me...

def c_locked(c)
  # We could write it the same we have been,
  # or we could write things more succinctly like so:
  return false if (c == 5 || c == 6)  
  # you could also say it as...
  # return (c != 5 && c != 6)
  # that's saying...return true if c is not 5 AND c is not 6
  # the first one is the opposite of that. it's just logic tricks.
