Interesting! Could you explain? What C features doesn't C++ have?

- C has its own syntax for generics

- C has broader support for designated initializers

- C allows implicitly casting void* to any other pointer type

- C has fewer keywords, e.g. you can use "friend" or "class" as identifier

- ...

Despite all this, it's true enough that one can easily write C code that also compiles as C++.

C has generics?

Nothing like C++ or Rust generics. C has _Generic (type-switch macro): https://en.cppreference.com/w/c/language/generic

Go into pointer qualifiers and const with _Generic and you'll see that it's a mess to do anything serious with it. But it's handy for type-generic math (tgmath.h style) and that's seems to be about it.
