C++ std::array

Modern alternative to C-style arrays, it's available from C++11.
It's a simple aggregate containing an array as its only member.

Some random things

• When you want to initialize an array
  • ❌ std::array<int, 10> array; $\to$ there will be garbage inside
  • ✅ std::array<int, 10> array = {}; $\to$ every element will be 0
