Cast Operator - Exercise

You should now be aware of four cast operators in C++:

1. static_cast
2. dynamic_cast
3. reinterpret_cast
4. const_cast

In each of the 4 given situations presented in the short program below, determine which is the most appropriate type cast to use and explain why you chose it:

class Base { virtual void foo(); ..... };
class Derived : Base { ..... }

void fcn(const Derived* ptr)
{
   void* p; 
    
   Derived* ptr_a = ______cast<Derived*>(p);
   ptr_a = _________cast<Derived*>(0xcafe);
   ptr_a = ________cast<Derived*>(ptr)
   Base* bptr = ______cast<Base*>(ptr_a);
}
