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.
