What are the advantages of using std::array in C++?

Using std::array in C++ provides several advantages, such as fixed size, better performance, and improved safety compared to raw arrays.

Can you explain how std::array improves safety?

Sure! std::array provides bounds checking with its at() method, which helps prevent out-of-bounds access, enhancing safety.

What about performance? How does it compare to other containers?

std::array is generally faster than other containers like std::vector because it has a fixed size and no dynamic memory allocation.

Are there any limitations to using std::array?

Yes, std::array has a fixed size determined at compile time, which means you cannot resize it dynamically like std::vector.

When should I choose std::array over std::vector?

Choose std::array when you know the size of the array at compile time and need better performance and safety.
