linked

The "linked" keyword in C++ is used in combination with the data structure "linked list". It is used to create a linked list of objects or nodes where each node contains a data element and a reference to the next node in the sequence. It is often used for dynamic memory allocation and can be more efficient than arrays for certain operations.

Here's a basic example of how "linked" is used in C++:

#include <iostream>
using namespace std;

class Node {
public:
    int data;
    Node* next;
};

int main() {
    Node* head = new Node();
    Node* second = new Node();
    Node* third = new Node();

    head->data = 1;
    head->next = second;

    second->data = 2;
    second->next = third;

    third->data = 3;
    third->next = NULL;

    Node* current = head;
    while (current != NULL) {
        cout << current->data << " ";
        current = current->next;
    }

    return 0;
}

In the example above, we define a Node class to represent each element in the linked list. In the main function, we create three nodes and link them together to form a simple linked list. We then traverse the linked list to print out the data stored in each node.
