Question

what does this output?

Derived *d = new Derived;
delete d;

and 

Base b;
Derived d;


given:
 class Base
     {
     public:
       Base()
       {std::cout << "Base Default Constructor" << std::endl;}
       Base(Base &base)
       {std::cout << "Base Copy Constructor" << std::endl;}
       virtual ~Base()
       {std::cout << "Base Destructor" << std::endl;}
       Base &operator=(const Base &base)
       {std::cout << "Base Overloaded Assignment" << std::endl;
        return *this;}
     };

     class Derived : public Base
     {
     public:
       Derived()
       {std::cout << "Derived Default Constructor" << std::endl;}
       ~Derived()
       {std::cout << "Derived Destructor" << std::endl;
     };

Answer 1

Derived *d = new Derived;
delete d;

Output of above code is

Base Default Constructor Derived Default Constructor Derived Destructor Base Destructor

==========================================

Base b;
Derived d;

Output of above code is

Base Default Constructor Base Default Constructor Derived Default Constructor Derived Destructor Base Destructor Base Destructor
