How do C++ STL vectors compare to arrays?

What are the main differences between C++ STL vectors and arrays?

C++ STL vectors are dynamic and can resize, while arrays have a fixed size. Vectors also provide more functionality.

Can you explain the advantages of using vectors over arrays?

Vectors offer automatic memory management, easier element insertion and deletion, and built-in functions for sorting and searching.

Are there any performance drawbacks to using vectors?

Yes, vectors may have overhead due to dynamic resizing and memory allocation, but they are generally efficient for most use cases.

When should I prefer using arrays instead of vectors?

Use arrays when you know the size at compile time and need maximum performance with minimal overhead.
