 | | A pointer may be associated with or aliased to various data objects (targets) during execution, or it may be undefined or null (not aliased to any data object). | | | However, Cray pointers may not be available on new computer architectures. | | | Fortran 90 pointers are not currently available in CF77, but are available on the IBM RS/6000 cluster and will be available on most computer architectures in the near future. |

| | Embedded.com - References vs. Pointers |
| | If the pointer happens to be null at the time of the reference definition, the reference is a null reference. | | | A pointer, even a const pointer, can have a null value. | | | Technically, the error is not in binding the reference, but in dereferencing the null pointer. |

| | Cprogramming.com Tutorial: Pointers |
| | Pointers require a bit of new syntax because when you have a pointer, you need the ability to request both the memory location it stores and the value stored at that memory location. | | | For example, using pointers is one way to have a function modify a variable passed to it. | | | When 0 is assigned to a pointer, the pointer becomes a null pointer, in other words, it points to nothing. |

| | Pointers |
| | Pointers have been used to implement reference parameters on the run-time stack, arrays names were seen as pointers, and the this pointer was used with objects, just to name three uses. | | | Pointers also come into play when we want to allocate a chunk of memory while our program is running. | | | A pointer is probably implemented as the main memory address (or some variation on this) of the item to which it points. |

| | What`s the Address? Pointers |
| | A pointer that is assigned NULL is called a null pointer. | | | However, with a pointer, the data type in the declaration means something different, namely the data type of another variable (or constant) whose memory address is the value of the pointer. | | | However, the meaning of the pointer’s data type is quite different than the meaning of the data type of a variable which stores a value rather than an address. |

| | The reason we associate a pointer to a data type is so that it knows how many bytes the data is stored in. | | | We are allowed to set a pointer reference since 4 bytes are set aside for any pointer. | | | When we increment a pointer we increase the pointer by one ``block'' memory. |

| | In addition to sporting pointer syntax and semantics, smart pointers often perform useful tasks—such as memory management or locking—under the covers, thus freeing the application from carefully managing the lifetime of pointed-to objects. | | | In some cases, a smart pointer might aggregate some handles to data and compute the pointer on the fly. | | | A smart pointer is a C++ class that mimics a regular pointer in syntax and some semantics, but it does more. |

| | Smart Pointers - What, Why, Which? |
| | Although it is possible to implement optimized allocation schemes using class-specific new and delete operators, smart pointers give you the freedom to choose whether to use the optimized scheme for each object, instead of having the scheme set for all objects of a class. | | | It is therefore possible to match the allocation scheme to different operating environments and applications, without modifying the code for the entire class. | | | When some part of the program tries to modify the object ("write"), the COW pointer creates a new copy of the object and modifies this copy instead of the original object. |

It's true that many people have various problems with pointers, and that many programs founder on pointer-related bugs. | | | Actually, though, many of the problems are not so much with the pointers per se but rather with the memory they point to, and more specifically, when there isn't any valid memory which they point to. |
