Kevin, your code looks good! Just a few suggestions for your issue on ex5. Good luck! Let me know if I can help with anything.

Nice, I like how you experiment with pointers here.

I see you changed the spacing here, good. It's funny how something as small as spacing can give you clues about who the author of the code was.

Oh. I love to use Prettier and format-on-save. As a highly visual learner it gives me a holistic impression of what good code should look like in each language.

Try taking your wait() call out of the for loop and see if that stops the program from hanging. You also might consider closing the "write" side fo the pipe with the close() call (also done outside of the for loop)although, I think that's less likely to be the issue.
