Define a function makeDeck with the following prototype:

cardT $*$makeDeck$($void$)$;

It should link a list of $52$ cardTs, one of each combination of rank $1-13$ and suit C$,$ D$,$ H$,$ or S and return the head of the list.

Use the makeCard and addToPile functions as described above $($they have already been defined here$).$
