C++: Linked Lists vs Arrays

What are the main differences between linked lists and arrays in C++?

The main differences include memory allocation, access time, and flexibility. Arrays have fixed size and faster access, while linked lists are dynamic and allow for efficient insertions and deletions.

Can you explain how memory allocation works for both?

Sure! Arrays allocate a contiguous block of memory, while linked lists allocate memory for each node separately, allowing for dynamic sizing.

Which one is better for large datasets?

It depends on the use case. If you need fast access and know the size in advance, arrays are better. For frequent insertions and deletions, linked lists are more efficient.

What about performance in terms of time complexity?

Arrays have O(1) access time, while linked lists have O(n) for access. However, linked lists have O(1) for insertions and deletions, compared to O(n) for arrays.
