Problem Set 1

Collaboration on problem sets is not permitted except to the extent that you may ask classmates and others for help so long as that help does not reduce to another doing your work for you, per the course’s policy on academic honesty.

What to Do

Log into submit.cs50.io using your GitHub account and click Authorize cs50, then close the tab.
Log into cs50.dev using your GitHub account to access your very own “codespace.”
Once your codespace has loaded, close any Welcome tabs that might have opened by default.
Run update50 in your codespace’s terminal window to ensure that your codespace is up-to-date and, if prompted, click Rebuild now.
Complete Hello, World.
Submit Hello, It’s Me.
Submit one of:
- this version of Mario, if feeling less comfortable
- this version of Mario, if feeling more comfortable
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 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!
