How to Get Help

Advice

  • Try out any of David’s programs from class via Week 1’s source code.
  • See CS50’s style guide for C for tips on how to improve your code’s style.
  • If you see an error message that you don’t understand, try asking help50 for help. For instance, if trying to compile hello, and
    make hello
    

    is yielding errors, try running

    help50 make hello
    

    instead!
