Better? -- @M Squared: Yes, yes he did :D

@John - Thanks

Answer 2

Thanks John! I had heard that it is/can be interpreted as an integer or something like.

Answer 3

meh. without hints\directions I wouldn't have got it.
if Binary comes up with something that works first go, I say he wins :)

Answer 4

I wonder if I should be using 0 as the initial value like in those examples? anyone know why they have used 0. It is of my understanding that 0 is not the same as NULL or nullptr

am I misinformed?

Answer 5

back to the drawing board :)

Answer 15

lol

I cannot post mine.

I feel it is too close to the original.

Answer 16

nullptr is normally 0, but is implementation dependent so isn't guaranteed.

Answer 17

I used a C++ compiler that used -1 as nullptr as 0 was a valid value. It was used for programming the os so had to be able to reference every addressable physical address. Of course, I really mean unsigned all bits set.

Answer 18

Jay, you haven't allocated the instance.
