array of N pointers to functions returning pointers to functions

Question

This was asked to me in an interview! i really got confused

• How do I declare an array of N pointers to functions returning pointers to functions returning pointers

Answer 1

Divide big problem into smaller parts:

/* char_func_ptr is pointer to function returning pointer to char */
typedef char* (*char_func_ptr)();

/* func_func_ptr is a pointer to function returning above type */
typedef char_func_ptr (*func_func_ptr)();

/* the_array is array of desired function pointers */
func_func_ptr the_array[42];
