Answer 1

Some compilers aren't fully C++ standard compliant. What you pointed out is possible in MinGW (iirc), but it's not possible in most other compilers (like Visual C++).

What actually happens behind the scenes is, the compiler changes your code to use dynamically allocated arrays.

I would advice against using this kind of non-standard conveniences.
