std::array
std::array is a fixed-size container that wraps around a traditional C-style array. If you’re coming from a C background or even early C++, you’ll be familiar with the headaches of raw arrays—the lack of bounds-checking, the cumbersome syntax, and more. With std::array, you get all the benefits of a traditional array, such as static memory allocation and constant-time access, while enjoying modern C++ amenities including range-based for-loops and member functions for size checking. Use std::array when you know the size of your dataset in advance, and it will not change. It’s perfect for scenarios where performance is paramount and your memory needs are static.
