What dose it mean head==NULL in linked list?? Help me please

Question

I know its empty but how?
Does it mean that the head address is (empty) or there no info(value) in the head?

Answer 1

Jein
when head==NULL is true, it means that head is not assigned any location in the memory.. since it is a struct type, it will be assigned a reference. Through that reference you can access its data or values. So null means not have any reference or memory.
