Answer / kar4you

Answer: We have a three ways for declaring techniques:

1. char *(*(*a[P])())();

2. Build the declaration up in stages, using
typedefs:
typedef char *pc; /* pointer to char */
typedef pc fpc(); /* return function pointer to char */
typedef fpc *pfpc; /* pointer to above */
typedef pfpc fpfpc(); /* returning function */
typedef fpfpc *pfpfpc; /* pointer to*/
pfpfpc a[P]; /* array of*/

3. Use the cdecl program, which turns English into C and
vice versa:
cdecl> declare a as array of pointer to function returning
pointer to function returning pointer to char
char *(*(*x[])())()
