Automakers issue recalls to fix defects, or sometimes just to check for defects. When a model is recalled, the automaker contacts every owner of that model by mail, and asks him or her to bring his or her car to a dealer. The dealer replaces defective parts at no cost to the car owner.
C++ Pointer Operators. C++ provides two pointer operators, which are (a) Address of Operator & and (b) Indirection Operator *. A pointer is a variable that contains the address of another variable or you can say that a variable that contains the address of another variable is said to point to the other variable. A variable can be any data type including an object, structure or again pointer itself. The . (dot) operator and the -> (arrow) operator are used to reference individual members of classes, structures, and unions.

C++ also has the concept of virtual functions which are member functions that can be overridden in derived classes and allow for dynamic dispatch. Virtual functions. Virtual functions are the means by which a C++ class can achieve polymorphic behavior.
