The superhero struct wonderwoman (int) isis (superhero *) superman (int *[]) I use short

The superhero struct wonderwoman (int) isis (superhero *) superman (int *[]) I use short internal arrows to remind myself which elements are uninitialized pointers. If a pointer is set to null, you should represent it with a line through the box, like so:

superhero marineboy[2];

superhero marineboy[2];
