Advice

• Try out any of David’s programs from class via Week 2’s sandboxes.
• 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 hello, and

  make readability
  

  is yielding errors, try running

  help50 make readability
  

  instead!
