Program Plan Intro

List or Linked list:

Linked list is a linear and dynamic data structure which is used to organize data; it contains sequence of elements which are connected together in memory to form a chain. The every element of linked list is called as a node.

List head:

List head is a pointer used to point the first node in the linked list and it is also called as “head pointer”; if the “head pointer” points to a “NULL” value, then it is considered that the “list is empty”.

Graphical representation of linked list:

The graphical representation of a linked list is as follows:

cout statement:

“cout” stands for standard output stream.

  • It is the c++ stream used to access the standard output, which in this case is the output screen.
  • “cout” statement is followed by the “<<” operator which is called the insertion operator.
  •  “<<” operator inserts the information that tails it into the stream and user can provide the required output.

card_t * moveCardBack (card t *head); The moveCardBack function will take the card in front of the pile and place it in the back. In coding terms, you are taking the head of the linked list and moving it to the end. The function has one parameter which is the head of the linked list. After moving the card to the back, the function returns the new head of the linked list.
The definition of linked list is given as follows: struct Node {    ElementType Element ;    struct Node *Next ; } ; typedef struct Node  *PtrToNode, *List, *Position; If L is head pointer of a linked list, then the data type of L should be ??
#include using namespace std; struct ListNode { string data; ListNode *next; }; int main() { ListNode *p, *list; list = new ListNode; list->data = "New York"; p new ListNode; p->data = "Boston"; list->next = p; p->next = new ListNode; p->next->data = "Houston"; p->next->next = nullptr; // new code goes here Which of the following code correctly deletes the node with value "Boston" from the list when added at point of insertion indicated above? O list->next = p; delete p; O p = list->next; %3D list->next = p->next; delete p; p = list->next; list = p->next; delete p; O None of these O p = list->next; %3D list->next = p; %3D delete p;
