Static variables can not be initialized in a class as class is building block of the object and you can not allocate memory for class but of class object. Static variable needs to be initialized outside the class.

pure virtual member function is a member function that the base class forces derived classes to provide. Normally these member functions have no implementation. Pure virtual functions are equated to zero
