(Note that this problem would have existed even if we were using normal pointers instead of smart pointers.) We should not delete the Person class pointer unless no body is using it. How do we do that? Implementing a reference counting mechanism in our smart pointer class will solve this ...
In this example, we will declare an integer variable and an integer pointer that will store the address of the integer variable. #include<iostream>usingnamespacestd;intmain(){inta;//normal integer variableint*ptr;//integer pointer declaration//pointer initializationptr=&a;//printing the address ...

And, do not abuse pointers in C++. Most probably member pl need not be a pointer. If you need collection of (vector, list, etc) of polymorphic types, take a look at Boost.PointerContainer Share Improve this answer Follow answered Oct 18, 2011 at 0:58 sly 1,77011 gold badge1010 ...
