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.
Like Java, C++ requires that you pass an object by pointer or by reference in order to call virtual functions. However, in Java, objects are always passed by reference so there is no need to have explicit syntax for it.
