auto vs auto*
When you use static_cast, wouldn't it be better to use auto instead of auto*?
auto* obj = static_cast<Class*>(object); // vs auto obj = static_cast<Class*>(object);
It would have the same result. Yes, * marks the variable as a pointer but
from the cast we can see that it is a pointer nonetheless.

- It doesn't really matter, but I personally find using auto* more readable. This one star doesn't change anything, it doesn't cost much, and it always makes the code more readable at first glance, without having to look at the entire line to know that it will be a pointer. -- FileEX (talk) 01:44, 26 June 2024 (UTC)
