What Member function places a new node at the end of the linked list?

Bappend Node

CDisplayNode

DStructNode

ENone of these

| | | Asked In BOA (Bank of America) |

Explanation:

The appendNode() member function places a new node at the end of the linked list. The appendNode() requires an integer representing the current data of the node.

To create a linked list, we can allocate space and make something point to it, by

writing:

struct-narne *pointer-variable;

Which of the following statement will correctly allocate the space

Apointer-variable= malloc(sizeof(*struct-narne));

Bpointer-variable = malloc(sizeof(struct struct-name));

Cpointer-variable = a!loc(sizeof(struct struct-name));

Dpointer-variable = alloc(sizeof(*struct-name));

Assume single linked list pseudo code as follows?

struct Node {
data
next
}
record List {
Node firstNode
}

function1(List list) {
obsoleteNode = list.firstNode; list.firstNode = list.firstNode.next; free obsoleteNode;
}

function2(node node) {
obsoleteNode = node.next; node.next= node.next.next; free obsoleteNode;
}

function3(Node node,Node newNode) {
newNode.next = node.next;node.next= newNode
}

function4(List list, Node newNode) {
newNode.next = list.firstNode; list.firstNode = newNode;
}

Afunction1 removes the first node

Bfunction2 removes node past this one

Cfunction3 inserts newNode after node

Dfunction4 inserts newNode after current first node
