What are the best practices for using std::array in C++11?

When using std::array in C++11, it's best to initialize it at the point of declaration, use it for fixed-size arrays, and prefer it over C-style arrays for better type safety.

Can you give an example of initializing std::array?

Sure! You can initialize it like this: std::array<int, 3> arr = {1, 2, 3}; This creates an array of three integers.

What are the advantages of std::array over C-style arrays?

std::array provides better type safety, bounds checking with the at() method, and integrates well with STL algorithms, making it more versatile.

Are there any performance considerations I should be aware of?

Generally, std::array has similar performance to C-style arrays since it is a lightweight wrapper. However, it offers additional safety features.
