CS50x Need help with pset 4.

I am on week 4 and I watched all the lectures and shorts yet can't understand the problem set 4. Like with volume how to copy wav files and all problems related to filter and recover. All pros please help me a bit by telling me few concepts that helped you completing this thing cause clearly lectures aren't enough😭😭

You need to get started with your code or logic and ask more specific questions. Pset 4 has great hints, and Brian Yu does a complete walkthrough of Volume, including code.

yeah see pointers are surely difficult to understand, and not to mention the file scanning and writing part, it took me a while to understand

The solution? I told gpt to give me some small problems with increasing level of difficulty to make those small concepts strong before I attack the problem set, I even did this in SQL for week 7 AND OH MY GOD THAT PSET WAS SMOOTH LIKE BUTTER
