When the head pointer points to null, it signifies an empty list.
Pointers to a single struct objectUntil now, we've used pointers to point to arrays of objects, rather than individual objects. It turns out that pointers to individual objects are very important in a wide range of circumstances.new and deleteYou can allocate a single object of a given type by just leaving the square brackets off the new statement. For example, to create a single point object and a pointer, p, that points to it, we could write:point* p = new point;To delete the point that p points to, you use the usual delete statement, except without the square brackets.delete p;operator ->In order to access a data-member of a struct from a pointer, one can use the -> operator. The pointer goes on the left, the name of the data member goes on the right. For example: point* ptr = new point; ptr->x = 0; ptr->y = 0;Video liên quanLinked List | Set 1 (Introduction)Like arrays, Linked List is a linear data structure. Unlike arrays, linked list elements are not stored at a contiguous location; the elements are linked using pointers. Show Why Linked List? C
