Well, yes.  This is rather wordy, but indeed it does the same thing.

Because C is a simple language.  That's a feature: if you want more
language complexity, and C++ can already do what you want, what not
use C++?  The usual argument is "I don't want all this other stuff."
Well, don't use it, then!

There seem to be many people who what what C++ can do, but say "I don't
want to use C++."
