What to Do

1. Log into submit.cs50.io using your GitHub account and click Authorize cs50, then close the tab.
2. Log into cs50.dev using your GitHub account to access your very own “codespace.”
3. Once your codespace has loaded, close any Welcome tabs that might have opened by default.
4. Run update50 in your codespace’s terminal window to ensure that your codespace is up-to-date and, if prompted, click Rebuild now.
5. Complete Hello, World.

   • this version of Mario, if feeling less comfortable

8. Submit one of:
   • Cash, if feeling less comfortable
   • Credit, if feeling more comfortable

If you submit both versions of Mario, we’ll record the higher of your two scores. If you submit both Cash and Credit, we’ll record the higher of your two scores.

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 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 hello
  

  is yielding errors, try running

  help50 make hello
  

  instead!
