A pointer that doesn’t refer to any address of value but NULL is known as a NULL pointer. When we assign a ‘0’ value to a pointer of any type, then it becomes a Null pointer.

In C, a null pointer is a variable that has no valid address and is allocated to zero or NULL. Normally, the null pointer does not point to anything. NULL is a macro constant defined in several header files in the C programming language, including stdio.
