    Question of the day

    What the advantage of forward declaration?

    For example:
    In header_file.h

    typedef struct foo * fooPtr;

    In implement_file.c
      struct foo
           int x;
           int y;

    it helps with type checking most of the time. it's unlikely you'll make the same mistake twice in one program.
