Where are temporary object stored?

Question

IMO temporary objects are stored in dynamic (heap) memory, but I\'m not sure. Can you please confirm or deny my thoughts?

Answer 1

Most (if not all) implementations store them on the stack (i.e. automatic storage), although I don't think the standard mandates anywhere. It's certainly easier to do it like that, as the compiler has to guarantee the temporary variable's life time, and it is possible that said lifetime will encompass a recursive call of the same function, creating another instance of the temporary variable.
