Please respect the spirit and the letter of Stanford’s honor code. You’re welcome to talk to classmates about labs conceptually, but the implementation must be your own unless otherwise noted. For example, speaking with a classmate about why some bug might be present in your program is okay as long as your classmate doesn’t share with you a program that fixes your bug. You should not use any existing code that we don’t supply, whether it is online or otherwise. Further, copying verbatim from places like Stack Exchange is prohibited: you will learn much more if you write your own programs.
60% of your grade will come directly from passing the unit tests that are distributed with the lab. Another 20% of your grade will come from passing unit tests that were not distributed with the lab. The final 20% of your grade will come from a manual code quality and style pass: you should not have memory errors and you should follow the style present in the lab template. When in doubt, run your program through Valgrind and follow the relevant Google Style Guide.
You have 100 late hours per lab. If your lab is
n hours late, your score on
the lab will be capped at
max(0, 100 - n)%. Hence, the later you are, the
better off you are submitting an imperfect assignment. For instance, if you
submit 12.7 hours late and receive a base (before adjustment) score of 72%, your
score will be capped at
max(0, 100 - 12.7) = 87.3%, so the final score will be
the full 72%. Similarly, if you submit your assignment 28.2 hours late and
receive a base score of 95%, your final score will be capped at
- 28.2) = 71.8%, and so your score will be 71.8%.
Each lab should contribute about 3 hours of work a week. If you are investing significantly more time than this, it is likely prudent to ask for help at office hours or via email.
You may be wondering why CS240 has decided to add labs to its curriculum. Quite simply, we want you to practice what you learn. We believe complex systems’ concepts are best and most easily understood when they are implemented.
