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.
Meaning of *& and **& in C++. That is taking the parameter by reference. So in the first case you are taking a pointer parameter by reference so whatever modification you do to the value of the pointer is reflected outside the function. Second is the simlilar to first one with the only difference being that it is a double pointer.
