Construction of a void Type?

Question

I was given a piece of code that uses void() as an argument. The code doesn\'t compile... obviously?

Can we instantiate anything of type void

Answer 1

C++ (and I say C++, not C) allows (§6.6.3 comma 2) functions with void return type to return a void expression, that is:

void foo() { return void(); }

But notice it is not constructing a temporary void!
