Why is it so that we can have virtual constructors but we cannot have virtual destructors?..

Answer / rdl

We can have Virtual Destructor. We cannot have virtual
constructor, becoz, if the constructor is virtual, in
polymorphism, there may be a chance for the base class
constructor not to get executed. so the entire class will
not be available.
