In the mean time we spend our time debugging the runtime because the virtual functions don't behave as expected. In C we know what is going on, in C++ it is pray and hope.
That is pure bullshit. All major browsers are written in C++, all major office suites, one leading free desktop, google, countless other projects. There is a lot more C++ code in the world than C code. If virtual functions didn't behave as expected, surely we'd hear by now.
