A
Pointer is a common data type in
computer programming. It holds the memory address of another element in the program, or a
null value.
Pointers are often used to hold the base address of
arrays and to make links between
nodes in
trees and
linked lists.
Some
programming languages (such as
assembly language and
C) allow some limited arithmetic on pointers.
Other languages (such as
Scheme and the
Java programming language) do not allow such arithmetic, treating pointers as an opaque type; such languages commonly refer to pointers as
references.
