Just a really quick question arising from pg. 69 after the treatment on NULL.
It says : [quote]“Later, when you are learning about pointers to objects, you will use nil instead of NULL. They are equivalent, but Objective-C programmers use nil to mean the address where no object lives”[/quote]
If NULL is zero, I’m assuming nil is zero also. Can I think of it as an address represented by 0?
So if you were to assign an object to nil, you are at least initialising it to a non-address, as in a non-‘working’ address? Is that correct? Albeit without setting it a value?
