         7,9     m&n sent to funW, but only the second of funW's 
                 parameters is a reference parameter; only n is increased.

         5,5,6   whole array is given to funY and funY can change anything
                 funY changes the first element (4->5)
                 funY calls funX which receives a copy of second element,
                 so second element, array[1], is not modified
