How the pointer used in the linked list?
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 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 fields of a node in a linked list?
usually we have two fields they are data field and node i.e. pointer field.it also depends on type of linked list.the above said is for single linked list.And for double linked list it sontains three fields first pointer that pointes to previious node and data field and another pointer that point to next node
How do you remove record file in linked list by using C?
You need to make the previous record's next pointer point to the record you are removing's next record, and (if it is a doubly linked list) the next record's previous pointer point to the record you are removing's previous record. If you are keeping track of the head and/or tail of the list, you need to make sure you update them if you have just removed one of them.
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.

How can a binary tree be converted into a doubly linked list?
To convert a binary tree into a doubly linked list, perform an in-order traversal of the tree and adjust the pointers to create the doubly linked list. This involves setting the left child pointer to the previous node and the right child pointer to the next node in the list.
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 delete node from acircular linked list?
Three steps for deleting a node from a linked list: 1) set currentNode->prev->next to currentNode->next (i.e. the previous node's next pointer should be the current node's next pointer). 2) set currentNode->next->prev to currentNode->prev (i.e. the next node's previous pointer should be the current node's previous pointer). 3) Free the memory used by currentNode (using delete, for example).
How are the members in the linked list liked together?
Usually each member has a pointer storing the address of the next element.
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 singly linked list and doubly linked list?
Singly Linked list Each item in the list is called a node and contains two fields  Information field - The information field holds the actual elements in the list  Next address field- The next address field contains the address of the next node in the list. The entire linked list is accessed from an external pointer called the List. Doubly linked list is a collection of node. Each node contains three fields an info field that contains the information stored in the node. The left and right field that contains the address of the node on its left and right. The doubly linked list could be linear, circular and may have a header node.
How do you remove record file in linked list by using C?
You need to make the previous record's next pointer point to the record you are removing's next record, and (if it is a doubly linked list) the next record's previous pointer point to the record you are removing's previous record. If you are keeping track of the head and/or tail of the list, you need to make sure you update them if you have just removed one of them.
How do you implement a doubly linked list by using singly linked list?
Add another pointer to the nodes for the previous node: struct node { struct node *next; struct node *previous; void *data; }; typedef struct node node; Then change the logic for insertion and removal to make sure you set the previous pointer as well as the next one.
Advantage and disadvantage of linked list?
Linked list is a dynamic data structure that contains a "link" to the structure containing the next item. It is a collection of structures ordered not by their physical placement in memory (like array) but by logical links that are stored as part of the data in the structure itself.Advantages of Linked Lists- Dynamic structure (Mem. Allocated at run-time).- We can have more than one datatype.- Re-arrange of linked list is easy (Insertion-Deletion).- It doesn't waste memory.Disadvantages of Linked Lists- In linked list, if we want to access any node it is difficult.- It is occupying more memory.
