In C, strings are just basic arrays which themselves are just pointers. There’s no safeguards there like we have in Java, so we need to write the guardrails ourselves, because failure to do so result in errors. If you didn’t know about it, a buffer overflow may be unexpected, but you don’t need to go and memorize the entire gcc codebase to know. Just knowing the semantics is enough.

The same thing happens with optimization. They usually warns about the gotchas, and it’s easy to check if the errors will bother you or not. You dont have to do an exhaustive list of errors when the classes are neatly defined.
