CMU 15-112: Fundamentals of Programming and Computer Science
Check3: Due in Autolab by 10am Tue 31-Jan

• Please read all the directions carefully before starting!


• This check should take 1-2 hours to complete. Please do not hurry through this.


• Again: it's really important that you stop the videos as you go, and try out the code yourself. You can do this directly in the browser. Run the code examples. Then, edit them slightly and predict what will happen, then run the edited code to confirm. Learning is not a spectator sport. Get in the game, work the code, play with it, explore, learn!


• This check should be completed collaboratively, in small groups (no size restrictions, but be reasonable).


• If you need group members, please fill out this form.


• That said, you may work solo if you have special circumstances, such as if you are traveling this weekend. Note that simply not wanting to work in a group is not a special reason to work solo. All special reasons for solo work on this check must be pre-approved in email from an instructor.


• To start:
  0. First, if you have not done so already, please take a brief moment to fill out this week2 time report. We very much need and value your thoughtful and accurate feedback. Thanks!
  1. Download the file check3.txt
  2. Be sure to track your time as you go, and to answer the questions in the check3.txt file as you go rather than after watching all the videos. Edit the check3.txt file directly, as you will submit that file when you are done.
  3. Carefully watch all the videos in these notes: Strings.
  4. Answer all the questions in the check3.txt file.
  5. When you are done, upload your completed check3.txt file to Autolab. Be sure to click on "check3", and be sure to submit this before Tuesday at 10am. No late submissions will be accepted.
