How to Get Help

  • Browse or search for answers on Ed!
  • Verbalize your logic to a rubber duck (whether actual or virtual!) and see if you hear any illogic in your own words!
  • Attend office hours!

  • Email heads@cs50.yale.edu!

Advice

  • Try out any of David’s programs from class via Week 2’s examples.
  • To see the manual pages for C functions, visit manual.cs50.io.
  • 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 readability, and
    make readability
    

    is yielding errors, try running

    help50 make readability
    

    instead!
