Unformatted text preview: as to the appropriateness of some discussion, contact the course’s instructor. You may turn to the Web for instruction beyond the course’s lectures and sections, for references, and for solutions to technical difficulties, but not for outright solutions to problems on problem sets or your own final project. However, failure to cite (as with comments) the origin of any code or technique that you do discover outside of the course’s lectures and sections (even while respecting these constraints) and then integrate into your own work may be considered academic dishonesty. All forms of academic dishonesty are dealt with harshly. If the course refers some matter to the Administrative Board and the outcome for some student is Warn, Admonish, or Disciplinary Probation, the course reserves the right to impose local sanctions on top of that outcome for that student that may include, but not be limited to, a failing grade for work submitted or for the course itself. Grades. Your work on this problem set will be evaluated along three primary axes. Correctness. To what extent is your code consistent with our specifications and free of bugs? Design. To what extent is your code written well (i.e., clearly, efficiently, elegantly, and/or logically)? Style. To what extent is your code readable (i.e., commented and indented with variables aptly named)? 1 < 16 This is CS50. Harvard College Fall 2010 Getting Started. Only a few checkboxes to go! SSH to and recursively copy ~cs50/pub/src/psets/pset5/ into your home directory. (Remember how?1) Then list the contents of ~/pset5/. (Remember how?) You should see the below. bmp/ jpg/ questions.txt As this output implies, most of your work for this problem set will be organized within two subdirectories. Let’s get started. If you’ve ever seen Windows XP’s default wallpaper (think rolling hills and blue skies), then you’ve seen a BMP. If you’ve ever looked at a webpage, you’ve probably seen a GIF. If you’ve ever looked at a digital photo, you’ve probably seen a JPEG. If you’ve ever taken a screenshot on a Mac, you’ve probably seen a PNG. Read up a bit on the BMP, GIF, JPEG, and PNG file formats.2 Then, in ~/pset5/questions.txt, tell us the below. 0. 1. 2. 3. How many different colors does each format support? Which of these formats supports animation? What’s the difference between lossy and lossless compression? Which of these formats is lossy ­compressed? Curl up with the article from MIT below.
