means pointer to pointer which gives value

so arrays of three function pointer

Its pointer of pointer concept so which gives value.

So arrays of three function pointer.

If one can give a more detailed description for this, I would appreciate it.

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].

What about [10] ? Is it 2-D array ?

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.

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.
x is an array of three function pointers.

Hi, please explain this in more simpler way.

Then what about [10], is it same as [3]?

What is the difference between an array of three-pointers and array of three function pointers?

Please tell me.
