Announcements

• Lab 1 is out and due Feb. 11
  • I don’t expect everyone to be done with Exercise 2 (getNumber) at this time, but if you’re feeling stuck and not making progress after this weekend, I encourage you to set up office hours with me Monday afternoon if you are available. You can use the office hours link below. Feel free to schedule another time if that doesn’t work or send me an email with times that work for you.
