Alternative Interpretation

Because declarations mirror use, a declaration can also be interpreted in terms of the operators
that could be applied over the object and the final resulting type of that expression. The type that
stands on the left-hand side is the final result that is yielded after applying all operators.

/*
* Subscripting "arr" and dereferencing it yields a "char" result.
* Particularly: *arr[5] is of type "char".
*/
char *arr[20];

/*
* Calling "fn" yields an "int" result.
* Particularly: fn('b') is of type "int".
*/
int fn(char);

/*
* Dereferencing "fp" and then calling it yields an "int" result.
* Particularly: (*fp)() is of type "int".
*/
int (*fp)(void);

/*
* Subscripting "strings" twice and dereferencing it yields a "char" result.
* Particularly: *strings[5][15] is of type "char"
*/
char *strings[10][20];
