Wrong.

1. pa is not a pointer to a function, it's a function which returns a
pointer. "()" has higher precedence than "*", so "*pa()" is parsed as
"*(pa())" (function returning pointer) rather than "(*pa)()" (pointer
to function).

2. An empty parameter list "()" indicates that the function takes
unspecified arguments. A function which takes no arguments has
"(void)" as the parameter list.
