How do I implement linked lists in C++?

How do I implement linked lists in C++?

To implement a linked list in C++, you need to define a node structure and then create functions to manage the list.

Can you show me a simple example of a linked list implementation?

Sure! Here's a basic implementation:

struct Node {
    int data;
    Node* next;
};

class LinkedList {
private:
    Node* head;
public:
    LinkedList() : head(nullptr) {}
    void insert(int value) {
        Node* newNode = new Node();
        newNode->data = value;
        newNode->next = head;
        head = newNode;
    }
};

What are the advantages of using linked lists over arrays?

Linked lists offer dynamic size, efficient insertions/deletions, and no need for contiguous memory, unlike arrays.

How do I traverse a linked list?

You can traverse a linked list by starting at the head and following the next pointers until you reach the end.
