Practice and Problems

• Practice:
  • Complete Hello, World
    • Make this in your practice folder
  • Submit Hello, It’s Me
    • Make this in a subfolder of practice called me and a file called hello.c
  • Complete Population Lab
    • Check: check50 cs50/labs/2023/x/population hopefully will work
    • Submit: submit50 cs50/labs/2023/x/population should work to submit, but may not check on submission
• Problem Sets:
  Inside a new subfolder folder as such unit0/pset create the following:
  1. Submit one of:
     • this version of Mario if feeling less comfortable
     • this version of Mario if feeling more comfortable
  2. Submit one of:
     • Cash if feeling less comfortable

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

Advice

• Try out any of the programs from class via the source code above
• 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!
