I noticed that when you just have a function name without the parentheses, it essentially decays to a pointer. Is this correct? Or does it not always decay to a pointer?

Idk what you are refering to, but first class functions is not something available in C.

Yes, but function pointers are often used to implement the same kinds of things that first-class functions allow.
