"pa" is a function returning a pointer to an array of four characters.

C declarations work by declaring an expression involving the
identifier as having a named type (in this case, "char").

"(*pa())[i]" is a character, for 0 <= i < 4.

Therefore:

"(*pa())" is an array of four characters.

Therefore:

"pa()" is a pointer to an array of four characters.

Therefore:

"pa" is a function returning a pointer to an array of four characters.
