Compare to this:

    #include <stdio.h>
    
    int main() {
        printf("Hello world!\n");
        return 0;
    }

Woo! Your first program and I count, at most, 2 things that could be described as "magic" for someone who's never seen C before (the stdio library and double quotes being syntactic sugar for an array of chars). Even then, those two things are deterministic, so they won't remain magical for long.
