Advice

  • Try out any of the programs from class via the source code above
  • 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!
