How do I choose the right container with std::array?

In C++, choosing the right container is crucial for optimal performance and functionality. The `std::array` is a fixed-size array that provides a simple way to store and manage a collection of items. It is ideal for scenarios where the number of elements is known at compile time and does not change during execution. This makes `std::array` a perfect choice for performance-sensitive applications as it allows for fast access and minimal overhead.

Here is an example of how to use `std::array` in C++:

#include <iostream> #include <array> int main() { // Create an std::array of integers std::array<int, 5> numbers = {{1, 2, 3, 4, 5}}; // Access elements for (size_t i = 0; i < numbers.size(); ++i) { std::cout << numbers[i] << " "; } std::cout << std::endl; return 0; }
