Answer 1

typedef is not a global variable, it’s simply an alias for another type. I usually use them for function pointers when I’m passing those around because writing them out every time is annoying.

typedef int (*function)(int, int);

I also use them to define a structure, union, or enumeration as a type

typedef struct {
    int x;
    int y;
    int z;
} Point;
