Or they've spent a lot of time in embedded systems development. Many of us write rather C-ish C++ because of the limitations of older compilers and the age of the code bases.

Genuine curiosity because I don't have a whole lot of experience with embedded systems: Why not just use C then?

Either way I would argue that using sizeof in that way is a sketchy practise.
