For a set-size array, use std::array, which isn't going to degenerate to a pointer when handed to some operate and does know its sizing.Such as, the overall swap() will duplicate the elements of two vectors staying swapped, Whilst an excellent distinct implementation will not likely copy things whatsoever.
If vector fits your requirements however, you don’t require the container being variable measurement, use array as a substitute.
