The return value of the function whose function pointer can be any of arrfptr[n]will be a pointer to an array of 10 characters.
The declaration can interpreted as "type of the array to be returned by function(char) (Returning char pointer(*)(function pointer name(*arrfptr)[size of the array of function pointers](3)(parameters)(void))[size of the array which will be returned from the function].

No. Its a single dimension array. Initially array is represented as the ptr array. I mean A[10]--->if you used A alone then it will become a pointer. So *(*(A then *(*(ptr of an array. Finally we can say it as three pointer function.

Array of three pointers means an array will contain three ponters which will points to three address space.
Array of three function pointers it means an array of size 3 which can stores the address of three functions.

typedef char (*(*arrfptr[3])())[10];
Meaning of this is
arrfptr is array of 3 function pointer which return array of 10 dimension whose type is char.
So,
x is an array of three function pointers.

Can anyone explain the program for understanding?
Because I understand x is an array of 3 function pointers, but I don't know how to implement it?

What is the difference between an array of three-pointers and array of three function pointers?
Please tell me.
Please tell me.

Its pointer of pointer concept so which gives value.
So arrays of three function pointer.
So arrays of three function pointer.

*(*
means pointer to pointer which gives value
so arrays of three function pointer
means pointer to pointer which gives value
so arrays of three function pointer
