typedef with function pointers

Hi!!
Can any one explain me the meaning of following notations clearly :

1. typedef char(*(*frpapfrc())[])();
frpapfrc f;

2. typedef int (*(arr2d_ptr)())[3][4];
arr2d_ptr p;

3. typedef int (*(*(*ptr2d_fptr)())[10])();
ptr2d_fptr q;

4. typedef char (*(*arr_fptr[3])())[10];
arr_fptr x;

5. typedef float *(*(*(*ptr_fptr)())[10])();
ptr_fptr y;

What are f,p,q,x,y?? and how?
Please don't just answer what they are explain then clearly..
Thanks in advance...
