Welcome to the world of Linked Lists!

Linked lists are linear data structures that store elements in a non-contiguous manner. Unlike arrays, which store elements in contiguous memory locations, linked lists use nodes to hold the elements and pointers to connect the nodes.

Let's take a look at the advantages of linked lists over arrays:

1. Dynamic Size: Linked lists can grow or shrink dynamically based on the number of elements added or removed. This makes linked lists more flexible compared to arrays, which have a fixed size.

2. Efficient Insertion and Deletion: Inserting or deleting elements in a linked list is more efficient compared to arrays. In linked lists, you just need to update the pointers, while in arrays, you need to shift elements to make space for the new element or fill the gap created by the deleted element.

3. Flexibility in Memory Management: Linked lists allow for efficient memory management. The elements can be stored anywhere in memory, and the nodes can be scattered across different locations. This allows for efficient memory allocation and utilization.

So, as you can see, linked lists offer several advantages over arrays. They are especially useful in scenarios where the size of the data is not known beforehand or when efficient insertion and deletion operations are required.

Now, let's dive deeper into the implementation of linked lists in C++. Take a look at the code snippet below:

xxxxxxxxxx

#include <iostream>

using namespace std;

​

int main() {

  // Linked List implementation

  // ... code here

​

  return 0;

}
