What are the differences between std::array and std::vector in C++?

What are the differences between std::array and std::vector in C++?

std::array is a fixed-size container, while std::vector is dynamic and can change size. Would you like more details?

Can you explain the performance differences between them?

Sure! std::array has better performance for fixed sizes due to no dynamic memory allocation, while std::vector is more flexible but may incur overhead.

When should I use std::array instead of std::vector?

Use std::array when the size is known at compile time and won't change. It's more efficient in such cases.

Are there any limitations to using std::array?

Yes, std::array has a fixed size, so you can't add or remove elements after creation. It's less flexible than std::vector.
