C++ is a better C

C++, with discretion, is a better C, and I do not recommend coding large projects in straight C.
There you have it. The man is a rocket scientist, just try and prove him wrong.

C++ is slower, as it indulges the use of smart-pointers and virtual classes everywhere. It also compiles slowly (about 3 slower than C) and changing a header would require whole program recompilation.
