There have been countless blogs about whether one should choose scanf/printf, or cin/cout as the main methods for getting inputs/outputs for C++. There are advantages and disadvantages of each kind, like the ability to easily format outputs, stream operator overloading, or not having to care about the decltype, etc.

But, from what I have seen, there are rarely any blogs that I can find myself, that mention the combination of cin/printf. This seems like a pretty good combination, and I have seen one or two people using it. One can get inputs without having to painfully type & every time, and nicely formatted outputs without a bunch of << operators.

Is there any disadvantage of this combination? Why do we hardly see anyone using those together?
