How does std::array perform compared to other containers in C++?

How does std::array perform compared to other containers in C++?

std::array is a fixed-size container that offers better performance than dynamic containers like std::vector due to its contiguous memory allocation.

What are the advantages of using std::array over std::vector?

The main advantages of std::array include lower memory overhead, faster access times, and no need for dynamic memory allocation.

Are there any scenarios where std::vector would be preferred?

Yes, std::vector is preferred when you need a dynamic size, as it can grow and shrink as needed, unlike std::array.

Can you give an example of when to use std::array?

Use std::array when the size of the array is known at compile time and remains constant, such as for fixed-size matrices.
