What is meant by linked list in c programming?

Java

Yes, a linked list can be implemented in an array. Instead of pointers (or references in Java) you can use element indexes in the "next" and "last" items.

This does not stop you from using pointers or references. They still work. You can take the address of an element of an array, such as &a[217], and place that in the .next or .last pointers, and manage the relationships in the normal way. Using an array is simply one way to manage memory.
