Placement-new address vs raw memory address?

Yes, they're the same. You might like to think of a memory address as a void pointer and of an object address as a typed pointer, but if you like, you can cast. In some sense new is the way to "convert" a memory address into an object (by constructing one).

Here's the full picture (note how there are no casts).

You're using void* operator new (std::size_t size, void* ptr) throw(); version of new operator. Here is what cplusplus.com says about this operator.

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.
