 C++ is efficient and abstract in one.

Any simple one-line claim here is clearly going to be wrong.
C++ code can be efficient, or abstract, or both, or neither.  The language supports a wide range of coding practices, including bad ones.
Some types of abstraction inevitably have run-time costs (speed or code space), which can be highly relevant in resource-constrained systems or other situations where efficiency is paramount (games programming is a fine example).  These abstractions may or may not be worth the cost in the overall picture - it is up to the software developer to figure that out, regardless of the language.

 

We very rarely see exceptions in this field, but OOP is certainly common now.

 You have to accept exceptions with C++ since there are a lot of places
where C++ throws a bad_alloc or system_error.

Incorrect.  Like most low-level or systems programmers using C++, I have exceptions disabled and never use them.

 

Classes with non-virtual inheritance are basically cost-free, and  provide
structure, safety, encapsulation and flexibility.  Virtual functions have
overhead, ...

 The virtual function overhead isn't notwworthy and not much more over
manual dispatch.

Incorrect.
You simply don't know what you are talking about for programming at this level - whether it is in C or C++.
Virtual function overhead will sometimes be worth the cost, and in some circumstances it can be less than more manual dispatch methods.  But it is not cost-free, and the overhead can most certainly be relevant if it is used inappropriately.

 

But you certainly can use a range of abstractions in C programming too.

 C doesn't supply features to have abstractions like in C++.

As I said, you can use a lot of abstractions in C programming, but C++ can make many types of abstraction easier, safer, and more efficient.

 

I don't think BM's posts are generally good or clear examples of uses
of C++. And I don't think continuously posting "C++ would be ten times easier" in c.l.c is helpful to anyone.

 C is just too much work.
