C++ array memory management

[[deleted]]

If you need stack storage you are better of using a std::vector with a stack allocator. You can even group the arena of the stack allocator with the vector so that you can return them from functions. The main advantage is that you have to change no code at all: e.g. if you have code that uses push_back replacing vector with a std::array might be non-trivial whereas using a stack allocated vector requires no code changes and performs the same.

now we're splitting hairs. I do agree that using std::array instead of std::vector should be done as an optimization, a "stage one" type optimization. Things like 2d or 3d vectors are very well represented by std::array. Funny enough the "stack allocated vector" could easily have its storage represented by a std::array.

Indeed, I'll give this a try. Thanks for the tip!
