The problem is unsolvable. In order to make C++ memory safe, the language has to be changed so much it might as well be a new one - requiring a rewrite of existing codebases.
If what we are talking about then is a completely new C++-like language, which will take a decade or more to develop, we might as well just use Rust, which is available right now and working surprisingly well.
This is exactly what Google and others have decided to do.
C++ is not going away, due to the staggering amount of existing code. But its usage will stop growing and then start to slowly shrink.
You never ever say Fräulein. It is disrespectful. 100 years ago it was a normal term to refer to an unmarried woman, but today it is rude, almost insulting. Please don't use that word, ever. It's Frau Müller for a woman and Herr Müller for a man, regardless of age and marital status.
If you want the waiter's attention, make eye contact, and give a nod or a subtle hand gesture. If they are obviously busy then wait.
Here we treat waiters mostly as equals. Imagine it as if an acquaintance or a neighbour was serving you - that's much closer to how you should treat them.
