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 askinghelp50
for help. For instance, if trying to compilehello
, andmake hello
is yielding errors, try running
help50 make hello
instead!
