In the last month, I’ve been active on the forum. I saw quite a lot of things like
final int b = 3, which means that
b does not change. But what do the others mean? I tried using
public int b = 123 inside of setup, but I received an error message. Similarly the
private String abc function also got an error message. Is it somehow related that the variables defined at the top of the code are public, while the ones inside of if statements, functions, classes, … are private?
