A linked list is normally specified by giving a pointer pointing to the first node of a list. An empty list has no nodes at all. What is the value of a head pointer for an empty list?
What will be an ideal response?
The null pointer value. The null pointer is obtained by assigning the int
constant 0 to a pointer variable. C++ provides a preprocessor constant NULL, which
evaluates to 0 for use in this situation.
