Hi All, It is possible to access a->reset() by runtime polymorphism concept in c++. But in ur code the assignment A *a = b is wrong. It should be A *a = &b; But I donot know what u mean by pure virtual class. If it is a class contianing some pure virtual methods then it is called abstract class. And remember to define the pure virtual functions in A in b. Otherwise B will also become abstract class and u cannot create its object. So the very statement static B b; will start throwing compilation error. But this is not the right forum to ask such question. Find some other C++ forum. thanks and regards, Pradip -----Original Message----- From: gcc-help-owner@xxxxxxxxxxx [mailto:gcc-help-owner@xxxxxxxxxxx]On Behalf Of Ishwar Rattan Sent: Friday, November 19, 2004 5:40 AM To: gcc-help@xxxxxxxxxxx Subject: Question on derived class? Assume that A is pure virtual class with some public methods. B is derived from A Class B : virtual A { public: // all methods of A are defined here + A new method is also defined (here only) -- call it reset() protected: // ... }; Now B is initiated as static B b; A *a = b; Is it possible to access b.reset() using a->reset()? -ishwar
