For example, its easier and less error prone to define structures with
virtual functions in C++ than write vtables manually in C. So, the adequate
subset of the C++ features can be useful to write more readable and
maintainable C-style code. These features are:
- abstract classes (well, structures with virtual functions);
- RTTI;
- lambda functions;
- constexpr functions;
- destructors;
- templates (very reservedly).
But these features should be avoided (as least for now):
- exceptions;
- the parts of the standard library which generates exceptions
(in particular, regex and thread).
