A node is an object in some kind of linked structure, such as a linked list or tree. Nodes can be allocated off of the free list and added to the linked list or tree at hand, and then filled in with the data needed to represent some piece of information. Conversely, they can be unlinked from the linked list or tree, and then returned to the free list when they are no longer needed. Often, there is no direct variable of pointer in the program's scope that represents the node; rather, the node can be found by traversing a list of linkages, list or tree, in the applicable data structure.
There are other definitions of "node", but this is the most common.

How can i find last node of a cicular list whose size i don't know and the last node points to any other node except first node of the link list through c plus plus language of data structure?

How do you edit a node in linked list C plus plus?
oh well. it is like this
Write a c plus plus code that insert a node in the middle everywhere?
Use std::list::insert_before().
What is a header node in c plus plus?
A header node, or head node, is a node that marks the start of a series of nodes, usually as part of a list or queue structure. The head node is often a sentinal that holds no data of its own. Sentinels are used to simplify algorithms by ensuring that a list can never be empty, even when it has no data.
How do you create a node in c?
It depends on what you mean by node. In great generality, I think it's malloc you might want to use.
What is typdef in c?
It is a keyword generally used to rename data types, using typedef you can create alias which can be used to declare the variable. e.g. typedef struct node { int info; struct node *next; }Node; now to declare variable of struct node type we can use the word Node in place of struct node
What is the mean c plus plus in machine code?
It is used to distinguish between the C or C++

How do you recursively reverse a singly linked list using c plus plus?
In this case recursion is not necessary, an iterative process is more efficient. Start by pointing at the head node. While this node has a next node, detach its next node and insert that node at the head. Repeat until the original head node has no next node. At that point the head has become the tail and all the nodes are completely reversed. The following example shows how this can be implemented, where the list object contains a head node (which may be NULL), and each node has a next node. The tail node's next node is always NULL. void reverse(list& lst) { if( node* p=lst.head ) { while(p->next) { node* n=p.next; // point to the next node p.next=n.next; // detach the next node n.next=lst.head; // insert the detached node at the head lst.head=n; // set the new head node } } }
Write a function in c plus plus to reverse a linked list without using more than constant of extra space?
assuming a circular, doubly linked list that uses itshead pointer as a sentinel (no data is stored in thehead).#define PTR_SWAP(a, b) \do { \const void* t = a; a = b; b = (void*)t; \} while (0)voidlistReverse(list_type* list) {node_type* node = list->head;do {PTR_SWAP(node->prev, node->next);node = node->prev;} while (node != list->head);}
Free download depth first search source code in java and c plus plus?
// Let's assume we're traversing an n-ary tree. // This interface is what each node in the tree implements. public interface Node { int getValue(); List<Node> getChildren(); } // Search the tree in depth public static List<Node> depthFirstTraversal(Node root) { // Create a list of nodes to process, starting with the root node. final List<Node> nodes = new LinkedList<Node>(); nodes.add(root); // Recursively add all children of all nodes of root to nodes for (Node n : root.getChildren()) { nodes.addAll(depthFirstTraversal(n)); } return nodes; }
In C plus plus Interface is also known as?
I guess you mean Java, there is no interface in C++.
