The pointer in linked list is used for traversing through the elements of the linked list. In a singly linked list, only a next pointer exits. So this pointer can be used for traversing only in one direction in the list. In case of a doubly linked list, a next and previous pointer exits. These pointers are used for traversing in both direction in the list.

What pointer type will you use to implement a heterogeneous linked list in c?
void pointer
What is difference between linked list and singly linked list?
Answersingly linked list has the node inserted only at one end. and the pointer corresponds to the next pointer.but in a doubly linked list, the node pointer points to the both previous and the next node.singly linked list has two nodesdoubly linked list has three nodesA doubly linked list makes sense when you need to traverse the list in both directions. You aren't able to do that with a singly linked list.
What are the basic types of link list in java?
linear circular double linked linear double linked circular Knowing the names does not help much when your teacher will require you to actually know what the names mean. Start reading. Programming requires lots of reading.
What are the linked list utility in memory management?
A simple linked-list is an approach is to store the freelist of memory blocks, where each node of the linked list contains a pointer to a single free block in the memory pool.
Need for header node in linked list?
The utility of a header node in a linked list is to simplify the functions of adding and deleting elements in the list. If you have a pointer in memory that points to the first element, then you need to pass the address of that pointer, rather than the value of that pointer, to the routines for list manipulation, because that pointer would need to change if an element were added or deleted at the head of the list. If that pointer, however, points to a special element in the list which is actually the pointer to the head of the list, then you do not need to pass the address of the pointer - you can pass its value, and it will never change. This technique "wastes" the data portion of that first element.
How do you check whether a linked list is circular?
A linked list is circular if the tail of the list points to the head. The easiest way to check this is to check whether the pointer of the tail is a null pointer. If it is, then the list is not circular.

32 can you create a linked list with out structure pointer?
Not in C, no.

What is link list and type of link list?
A linked list is a set of elements, usually structures, where each element contains a pointer or index to the "next" element, along with the data represented by the element.Often, the elements are allocated from the heap. Sometimes, a fixed number of elements is contained in an array. In the first case, pointers are used. In the second case, indices are used.Types of linked lists are ... In an array implementation, read pointer as index.Singly linked - there is a head pointer, and one next pointer per element. The last element's pointer is null. This type of list can be traversed in only one direction.Doubly linked - there is a head pointer, and each element contains two pointers, one to the previous element and one to the next element. This type of list can be traversed in two directions, making insertion and deletion a bit easier, at the cost of extra memory.Circularly linked - the same as Singly or Doubly linked, except that the last element's pointer points back to the first element's pointer. These types of lists are often used as queues.
What is heterogeneous linked list?
A heterogeneous linked list is a data structure where each node can store data of different types. This allows for a flexible way to organize and manipulate data that may vary in structure or content. Each node contains a pointer to the next node in the list, enabling traversal and manipulation of the data.
What is linked list in C langauage?
A linked list is a collection of items, often nodes, that are sequentially linked by some kind of index or pointer contained within each item.
What are the basic types of link list in java?

Write the concepts of linked list?
A simple linked list is built out of nodes. Each node consists of two sections, data and a pointer. The data contains whatever information that this node of your list needs to contain, and the pointer contains the memory address of the next node in your list.
How do you represented linked list in memory?
Memory Representation of Linear Linked List:Let LIST is linear linked list. It needs two linear arrays for memory representation. Let these linear arrays are INFO and LINK. INFO[K] contains the information part and LINK[K] contains the next pointer field of node K. A variable START is used to store the location of the beginning of the LIST and NULL is used as next pointer sentinel which indicates the end of LIST. It is shown below:
