If there's a dealloc call in more than one place, setting the object variable to nil makes sure it won't be deallocated more than once by mistake. Same logic if the function with the dealloc is called from more than one place, or can be called arbitrarily by external code (i. E.
Other classes).
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.
