How to Get Help

  • Browse or search for answers on Ed or post your own questions!
  • Browse the CS50 Manual Pages for functions that might be useful.
  • Watch Shorts for any topics that you still have questions about.
  • Attend office hours!


  • Try out any of David’s programs from class.
  • 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 plurality, and
    make plurality

    is yielding errors, try running

    help50 make plurality
