Is D Better than C?

So, D’s threading situation is far better than C++’s. D’s templates are far more powerful than C++’s templates, allowing you to do far more, far more easily. And with the addition of template constraints, the error messages are way better than they are in C++. D makes templates very powerful and usable.

What is %d in printf?
