How to do it...

We are going to define a structure that is composed of multiple members. Then, we allocate an instance of this structure on the heap that is maintained by a shared pointer. From this shared pointer, we obtain more shared pointers that do not point to the actual object but to its members:

1. We include the necessary headers first and then declare that we use the std namespace by default:

      #include <iostream>      #include <memory>      #include <string>            using namespace std;

2. Then we define a class that has different members. We will let shared pointers point to the individual members. In order to be able to see when the class is created and destroyed, we let its constructor and destructor print messages:

      struct person { string name; ...
