We have now many finished Lab 1 or about to report it. For those who still have the major parts of Lab 2 and 3 lagging behind the schedule, please prioritize Lab 5 (Testing&debugging) and then Lab 4 (Compiling&Linking) this week. It is preferred that you at least finish the first part of Lab5 (Part A: Simple testing of C functions) before the classroom exercise on Friday afternoon.
