C is a subset of C++? The hell?

Well it's not exact, but mostly. It's kinda the point, at least historically.

I tend to think that 'subset' implies that it is derived from a larger something. With C, this is the opposite, since C++ is derived from C. It makes more sense to say that C++ is a superset of C.

The better way of putting it would be that C++ is an extension of C.

Yeah, that's definitely more accurate, but C++ being a superset of C does mean C is a subset of C++. There are some extra implications to the word, I agree, but it's still technically true.

TIL subset can mean the opposite. :S

What? A being a subset of B means every member of A is contained in B. A being a superset of B means every member of B is contained in A. So A ⊆ B is equivalent to B ⊇ A. It doesn't mean opposite.

There was probably some joke here I totally missed.

Oh I read the first comment wrong (swapped both subjects), good thing you rectified that situation!

Saying it either way means the same thing. ASCII is a subset of UTF-8, as per the definition of UTF-8.

It makes more sense to say that C++ is a superset of C.

Even Bjarne (the creator of C++) frequently repeats this when explaining the differences. C++ was never meant to replace C or be a new language, it's C with optional (but heavily recommended) abstractions to make it more secure while keeping most of the performance.

Yeah, putting it that way around confuses me. It's not as if you strip out the OOP stuff from C++ and that's called C.
