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

Is this what you are looking for:

typedef char* charptr;
typedef charptr (*innerfun)();
typedef innerfun (*outerfun)();

const size_t N = 10;
outerfun my_outerfun_array[N];

I hope I got it correct, it seems a strange question to me especially in an interview :(
