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.
When the member-selection operator is used to access a member function, the this pointer argument has a type of class-name * const. If the members are declared as const or volatile, the types are const class-name * const and volatile class-name * const, respectively.or example, max(double, double) is considered the same as max(double &, double &) . Declaring two such functions causes an error. For the same reason, function arguments of a type modified by const or volatile are not treated differently than the base type for the purposes of overloading.
