voidNumber changes to voidPhone


A little something for the errata sheet:
In the code snippet at the top of page 336, the original void *voidNumber seems to change to voidPhone by the time it gets used throughout the example.


Noted – thanks!


I am not sure if it is another typo but I stumbled over “The reason it that…” in the second line of the big paragraph on page 336.
Shouldn’t it be called “The reason is that…” ?
