After dropping the phrase still in normal operation. } The new Heavy Stack is in the array. You called this new placement. Not simply new. You can manually implement dtor, you need not implement it. Because you are new to the system memory is allocated from the array on the stack. So at the end of the procedure when the system will recover memory, and your manual will result in run-time analysis of the structure (or not defined) behavior. You do not get through because of the new memory structure on I can accept why to analyze it. The new Heavy This is the C + + programming examples of thinking is certainly correct. If manual analysis of the implementation of structural function, structure function analysis will be deployed. But memory or automatic recovery. The new Heavy Ah, I have the wrong. Imagine delete go. Analysis of the structure is to be done. Call analysis shows the general structure will not function. Only do so with new placement. [ Closed window ]
