Consider putting every single definition within an implementation supply file in an unnamed namespace Except if that's defining an “external/exported” entity.

If you'll want to outline any of these five functions, this means you'll need it to complete over its default behavior – plus the 5 are asymmetrically interrelated. Here’s how:

unstable area variables are practically generally Completely wrong – how can they be shared with other languages or hardware when they’re ephemeral?
