Pointers

A pointer can be constructed by use of the address operator &
A pointer must be explicitly dereferenced if we want to access the target value of the pointer
- By means of the dereference operator *
In C you can work on both a pointer and the object pointed to
- Pointer arithmetic
A pointer of type T* to can point to a single value of type T, or to an array of T-values
- We cannot separate these two situations
For two different types T and S: T* is different from S*
Generic pointer type void*
NULL pointer value

Pointers are also important in C++

May instances of classes or structs are not accessed by pointers in C++

Polymorphic objects must be accessed by pointers, however

C++ smart pointers are introduced to avoid memory leaks and dangling pointers
