wouldn't 0 be 0 and -1 underflow to 255 if 8 bit container? intentional error to enhance engagement?
You're correct but you have an off by 1 error.
First, the genie grants the wish.
NumWishes=0;
Then, having completed the wish, the genie deducts that wish from the remaining wishes.
NumWishes--;
And to complete the thought,
Lastly, the genie checks if the lampholder is out of wishes
If(NumWishes==0) {...}
(255==0) evaluates to False, so we fall past that check.
Yeah, but what if the counter gets decremented before the wish gets granted, huh?
Didn't even get the joke here because this is how I always imagined genie wishes working.
