How does C++ handle performance with 2D arrays?

C++ handles 2D arrays efficiently, but performance can vary based on how they're implemented. Are you using static or dynamic arrays?

I'm using dynamic arrays. Does that affect performance?

Yes, dynamic arrays can introduce overhead due to memory allocation. Using a single contiguous block of memory can improve cache performance.

What about using vectors instead of raw arrays?

Vectors offer flexibility and safety, but they may have slightly lower performance due to additional features like bounds checking.

Are there any best practices for optimizing 2D array performance in C++?

Yes, consider using row-major order for storage, minimizing dynamic allocations, and leveraging cache-friendly access patterns.
