When should I use vectors in C++17?

Vectors in C++17 are dynamic arrays that can grow in size. Use them when you need a resizable array.

What are the advantages of using vectors over arrays?

Vectors offer automatic memory management, bounds checking, and a rich set of member functions for manipulation.

Are there any performance considerations I should be aware of?

Yes, vectors can incur overhead due to dynamic resizing. For large datasets, consider reserving space in advance.

Can I use vectors for multi-dimensional data?

Yes, you can use vectors of vectors to create multi-dimensional arrays, but consider using other structures for complex data.

What are some common use cases for vectors?

Common use cases include storing lists of items, managing dynamic collections, and implementing algorithms that require resizing.
