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.
Because of the way C/C++ uses pointers and arrays, you can reference an array element either by subscription or * (the unary dereference operator). int b[100]; // b is an array of 100 ints. int* p; // p is a a pointer to an int. p = b; // Assigns address of first element of b.
