Problem Set 2

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.

The staff conducts random audits of submissions to CS50x. Students found to be in violation of this policy will be removed from the course. Students who have already completed CS50x, if found to be in violation, will have their CS50 Certificate permanently revoked.

What to Do

Did you start CS50x in 2021 or prior? Be sure to follow these instructions if you haven’t already!

Log into code.cs50.io using your GitHub account
Run update50 in your codespace’s terminal window to ensure your codespace is up-to-date and, when prompted, click Rebuild now
Submit Readability
Submit one of:
- Caesar, if feeling less comfortable
- Substitution, if feeling more comfortable

If you submit both Caesar and Substitution, we’ll record the higher of your two scores.

Advice

Try out any of David’s programs from class via Week 2’s examples.
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!
