So it is an object-wrapper? And releasing of memory happens because of narrowed scopes?

the smart pointer like when there is no referance to it well be released from the heap examlpe: int *p = new int(5); // no. of ref to p is 1 int temp = *p; // no. of ref to p is 2 temp = 4; // no. of ref to p is 1 p = NULL; : // there is no referance to p // anymore... released safly (but of course it well be little bit more complicated)

yeah it also consider the method or the object scope it's just to privant memory leaks you may forget to release resources thats lead to memory leak
