Here is the corrected version of your question:
I watched this video (https://www.youtube.com/watch?v=WficzyoTSsg&t) to learn how to code a video game in C. I followed all the steps at the beginning of the video and downloaded all the files he mentioned. At 2:39, he opened the SDL-mixer file, and in the video, the guy had a directory full of different files.
However, when I downloaded the file on my PC, I got this directory:
I can only add the SDL2_mixer.dll file, but there is no .h file. I tried to download the same version as in the video, but I encountered the same issue (downloaded from here: https://github.com/libsdl-org/SDL_mixer/releases because on the SDL website, I got a page not found).
I hope someone knows how to help me get the correct version of SDL_mixer.
