OpenFrameworks
openFrameworks is a community-developed cross platform toolkit for creative coding in C++.
Try Cinder (https://libcinder.org/). I have not tried it myself but it seems to have the same goals as P5 and Processing (ie. creative coding).
I don't thinks so, but you can try sdl, sfml or learn any graphics libary (I would suggest opengl)
Maybe something like raylib could work, although its C99, not C++. https://www.raylib.com/
