  • Try out any of David’s programs from class via Week 4’s source code.
  • 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

    help50 make filter
