Unfortunately I think that this statement has some truth in it: I work in telecoms where we care about realtime: I was used to work in C but my latest project is in C++, I was curious about how C++ and realtime mix: the answer is quite poorly..

It's not that you can't do realtime in C++: it's that you have to fight against lots of C++ developers who want to apply the non-realtime C++ popular idioms.

For example: using interface classes for mocking objects with googletest, the result: virtual methods everywhere..
