(Codes need everything that makes an output)

I need help making codes to see how smart pointers work in:

1. Use smart pointers Objects that must be allocated with new, but you like to have the same lifetime as other objects/variables on the Run-time stack. Objects assigned to smart pointers will be deleted when program exits that function or block.

2. Use smart pointers Data members of classes, so when an object is deleted all the owned data is deleted as well (without any special code in the destructor).
