Array vs Linked List: Which to Use?

What are the main differences between arrays and linked lists?

Arrays are fixed-size and allow random access, while linked lists are dynamic and allow efficient insertions/deletions.

In what scenarios would I prefer to use a linked list over an array?

Use linked lists when you need frequent insertions/deletions or when the size of the data structure is unknown.

Can you give me an example of a real-world application for each?

Sure! Arrays are great for storing data like image pixels, while linked lists are useful for implementing queues or stacks.

What about performance? Are there any trade-offs I should be aware of?

Yes, arrays have better cache performance due to contiguous memory, while linked lists have overhead from storing pointers.
