They can compile more C11 code than C99, thanks to the stuff dropped in C11.

They also support most of the C standard library additions.

As of C++20, the biggest difference is that designated initializers must follow field declaration order, restrict and _Generic aren't supported, and the type safety semantics are stronger.

There's also a handful of small differences like this, e.g. in C it's possible to construct a value and take the address for a pointer argument right in the function call:

    func(&(bla_t){ .x=1, .y=2 });

This is completely valid C, but invalid C++ (C++ has references as "workaround" for such adhoc-constructed parameters which shouldn't be passed by value).

Yes, that falls under my "type safety semantics are stronger" part of the comment.
