Is this code incorrect re memory management? (re NSMutableArray addObject)?

If you've invoked autorelease on all of the objects that you've added to your array, there's no additional work for you to do in terms of memory management. The NSMutableArray will manage the in-memory state of the objects that are added to it (as in retaining them when added and releasing them when the object is removed from the array, either by explicitly releasing it or when the array is released). All you need to do is make sure you release the array when you're done with it.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
