The only reason I see that C++ is "better" for learning is it's object orientated. But that alone is hardly a good enough reason to choose C++ over other object-orientated languages. But the distinction for learning certainly depends on what's being taught and for what purpose.

But let's not step into another argument, (some) people are rather one-sided.

And a major reason for this has nothing to do with C or C++, but rather that most operating systems in use today were originally written some 10+ years ago by programmers with several years of experience - which meant that they started prgramming before the 1990's, most likely. Whilst C++ technically existed at that time, it was neither mature, nor commonly used.

And you CAN NOT write an OS in C or C++ alone. There will be some lines of assembler involved to do some of the tricky bits that deal with specific registers of the processor. And for most machines, there is a need to have a few instructions of assembler code to set up a suitable environment to run C itself.
