With computer memory, a null pointer is a command that directs software or the operating system to an empty location in the computer memory. The null pointer is commonly used to denote the end of a memory search or processing event. In computer programming, a null pointer is a pointer that does not point to any object or function.

A nil pointer is a false value. For example, 1 > 2 is a nil statement.

In the programming language C, NULL is an available command that can be used, whereas nil is an available command used in the Pascal programming language.
