How to Get Help

  • Watch Shorts for any topics that you still have questions about.
  • Attend office hours!

Advice

  • Try out any of David’s programs from Week 4.
  • If you see any errors when compiling your code with make, focus first on fixing the very first error you see, scrolling up as needed. If unsure what it means, try asking help50 for help. For instance, if trying to compile filter, and
    make filter
    

    is yielding errors, try running

    help50 make filter
    

    instead!
