— On 4:14, the where is the last(3rd) pointer pointing to?
At 6:27, why does the guy says that if there would be somebody holding reference then we would have a problem, What is the problem that he is talking about?
— Isn't v2 already a reference to the returned vector?
— End of allocated storage
— And what about the 2nd pointer, isn't it pointing to the same location?
— Second points to begin+size, in this case theyre same, usually they are different
— Because this somebody could suddenly start to work with moved-from object
— So, if there are actually 4 elements present in the vector and its size is 8 then the 3rd points to the 8th location and the 2nd pointer points to the 4th location?
— Yes
— Size is 4, capacity is 8
— 2nd is begin+size, 3d is begin+capacity
— Ok
