2. Array of pointers to objects    bytes.com

From employee i have derived four classes in which i define the pure virtual function no longer making them abstract. Nope, that's not it. If you want to create objects of your derived classes, you can not have pure virtual methods in there, only concrete methods or, in case you will derive from the subclass later, virtual methods. You need to ...
