Question

This is the question:
Using the Right-Left rule write the C definition of a variable named fubar that is a pointer to a function that
takes a pointer to a char and returns a pointer to an array of 7 elements where each element is a pointer to a
struct Sporcle.

My answer:

*( (Sporcle*)[7] ) ( *fubar )( char* );

Can anyone verify my answer and/or give me some pointers (no pun intended)?

Edited Answer:

( (struct Sporcle*)[7] ) *( *fubar )( char* );

Final Answer

struct Sporcle *(*(*fubar)(char *))[7];

Answer 1

Build it up a piece at a time:

A variable named fubar…

fubar

…that is a pointer…

*fubar

…to a function…

(*fubar)()

…that takes a pointer to a char…

(*fubar)(char *)

…and returns a pointer…

*(*fubar)(char *)

…to an array of 7 elements…

(*(*fubar)(char *))[7]

…where each element is a pointer…

*(*(*fubar)(char *))[7]

…to a struct Sporcle.

struct Sporcle *(*(*fubar)(char *))[7]

Your answer is incorrect – the thing on the left (called the declaration specifier) can only directly specify a type (a base type like int, a struct, union, enum or type name defined with typedef, optionally modified with a storage class specifier like static and/or a type specifier like const). Pointer, array and function types are constructed by modifying the right-hand-side of the declaration (called the declarator), by adding *, [] or () to it.

In this case, the declaration specifier is struct Sporcle and the remainder is the declarator.
