How exactly is the ctor() and dtor() related to new and delete. Surely, 
calling new and delete calles the ctor and dtor but i dont see how the reverse 
is true or even related.

I don't see how new() and delete() can be automatically included by the 
compiler.

Why would the compiler think delete() is needed unless delete is actually 
called in code?
