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.

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!
