When referring to computer memory, a null pointer is a command used to direct software or the operating system to an empty location in the computer memory. Commonly, the null pointer is 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, where nil is an available command used in the Pascal programming language.
