# Insert Node at the End of Singly Linked List

“** Insert Node at the End of Singly Linked List**” is very basic programming problem based on. of linked list data structures. Here, we are given a linked list and our task. is to add a new node is added at the end of the linked list.

**Example:**

Current Linked List: 1 -> 2 -> 3 -> 4 -> NULL After Inserting Node with Value ‘5’, the linked list become: 1 -> 2 -> 3 -> 4 -> 5 -> NULL

The steps required to insert the new node at the beginning of the linked list is as follows:

- Create a new node with the desired value in data part and NULL value in pointer part.
- Check whether linked list is empty or not.
- If linked list is empty, then the new node will become the head of the linked list.
- Else if linked is not empty, then traverse the whole linked list and reach to the last node of the linked list, then point the pointer part of last node of the linked list to the new node.

If the current linked list is {1->2->3}, then after inserting node with value 4, the newly linked list will become {1->2->3->4}.

**C++ Program insert new node at the end of the linked list is as follows:**

/* C++ Program to Insert New Node at the End of the Linked List */ #include<bits/stdc++.h> using namespace std; /* Structrue of the Node */ struct node { int data; struct node *next; }; /* Function to create New Node of the Linked List */ struct node *create(struct node **new_node, int ele) { (*new_node) = (struct node*)malloc(sizeof(struct node)); (*new_node)->data = ele; (*new_node)->next = NULL; return (*new_node); } /* Function to Insert New Node at the End of the Linked List */ void insert_end(struct node **head, int ele) { /*Creating a new node.*/ struct node *new_node; new_node = (struct node*)malloc(sizeof(struct node)); new_node->data = ele; new_node->next = NULL; /* check whether the linked list is empty or not*/ /* If empty, new node will become head of the linked list */ if(*head == NULL) { *head = new_node; return; } /*If not empty, we traverse the complete linked list and points the last node of the linked list to the new node */ struct node *temp = NULL; temp = (*head); while(temp->next != NULL) temp=temp->next; temp->next = new_node; } /* Function to Print the Linked List */ void print(struct node *head) { struct node *p = head; while(p!=NULL) { cout<<p->data<<" "; p=p->next; } } int main() { struct node *head; head = NULL; cout<<"Inserting 3 Nodes to the End of the Linked List!!"; insert_end(&head,1); insert_end(&head,2); insert_end(&head,3); cout<<"\nThe Nodes of the Linked List are: \n"; print(head); }

Inserting 3 Nodes to the End of the Linked List!! The Nodes of the Linked List are: 1 2 3OUTPUT:
