If a pointer is null, it means that it is not pointing to any valid memory location and thus, any attempt to access such a location would result in an error. Null in MathematicsIn mathematics, null is used to represent a zero value or a non-existent value. For instance, in set theory, a null set is a set that does not contain any elements. This is a fundamental concept in set theory and it is used in various mathematical proofs and theorems.In linear algebra, a null space of a matrix is the set of all vectors that when multiplied by the matrix, result in a zero vector. This is a key concept in linear algebra and it is used in solving systems of linear equations, among other things. The Significance of NullThe concept of null is significant in various fields.
