C++ STL: Vectors, Iterators, and 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 how iterators work with vectors?

Iterators allow you to traverse elements in a vector. You can use begin() and end() to get the start and end points.

Are there performance differences between using vectors and arrays?

Yes, arrays are generally faster for fixed-size data, while vectors offer flexibility at the cost of some performance.

When should I prefer using vectors over arrays?

Use vectors when you need dynamic sizing or additional features like easy insertion and deletion.
