  • NEW course grade preview statistics

    The course grade preview in your gradebook has been updated. It now includes assign0 through assign4 (assign5 grades will be out shortly--sorry for the delay due to midterm 2 grading), with on-time bonus and style grades, midterm 1, midterm 2 (each midterm weighted equally and neither dropped yet since it is the final that would take its place not the other midterm), and lab1 through lab8. For your information, the statistics for this for the class are as follows: median: 0.90, mean: 0.82, stdev: 0.20. The median letter grade in the course is typically a B+, but letter grades will never be assigned lower than 90=A-, 80=B-, etc. Hope this helps. Sun June 5, by Cynthia

  • assign3 now posted, but...

    Assign3 is now posted, but I would emphatically implore you to spend little to no time working on it until after the midterm. The midterm is worth more points than the assignment, and is a better investment of your time. You'll notice that you have the usual 7 days to work on assign3 even if you don't start until after the exam (not including grace period, which adds more time). I only posted it because some students have unusual schedule constraints such that it would make sense for them to choose the (otherwise less than optimal) route of working on it this week to free up time next week. ASSIGN3 HELP VIDEO: There will be an assignment walkthrough video available via the SCPD site. In the walkthrough video, I give a few pointers to get you started. It should post Wed or Thurs depending on when the SCPD staff gets to it. Tue April 26, by Cynthia

Course information

CS107 is the third course in Stanford's introductory programming sequence. Our CS106 courses provide students with a solid foundation in programming methodology and abstractions and CS107 follows on to build up their programming maturity and expand breadth and depth of experience. The course will work from the C programming language down to the microprocessor to de-mystify the machine. With a complete understanding of how computer systems execute programs and manipulate data, you will become a more effective programmer, especially in dealing with issues of debugging, performance, portability, and robustness. Topics covered include: the C programming language, data representation, machine-level code, computer arithmetic, elements of code compilation, optimization of memory and runtime performance, and memory organization and management.

The class has two lectures a week and a weekly lab designed for hands-on learning and experimentation. There will be significant programming assignments and you can expect to work hard and be challenged by this course. Your effort can really pay off - once you master the machine and advance your programming skills to the next level, you will have powerful mojo to bring to any future project!

Lectures: Mon & Fri 12:30-1:50pm in NVIDIA Auditorium.

Labs: Tue/Wed/Thu various times Gates B08
