When should I use arrays instead of vectors in C++17?

In C++17, use arrays when you need a fixed size and performance is critical. Vectors are more flexible but have overhead.

Can you explain the performance differences between arrays and vectors?

Sure! Arrays have a fixed size and are allocated on the stack, making them faster. Vectors are dynamic and allocated on the heap, which can introduce overhead.

What are the limitations of using arrays?

Arrays have a fixed size, meaning you can't change their size after declaration. They also lack built-in methods for manipulation.

Are there any scenarios where vectors are better?

Yes, vectors are better when you need dynamic sizing, easy insertion/removal of elements, and built-in functions for manipulation.
