Objective: Overload the input operator for the card class.
Instructions
Given the following code for a playing card ADT, overload the input operator >> for the card.
You do not need to handle all 52 cases, just indicate how you would have to handle them in case you where required to. 
#include  <iostream.h>

char  pips_symbol[14] = { '?', 'A', '2', '3', '4', 
  '5', '6', '7', '8', '9', 'T', 'J', 'Q', 'K' };
char  suit_symbol[4] = { 'c', 'd', 'h', 's' };

enum suit { clubs, diamonds, hearts, spades };

class pips {
public:
   void  assign(int n) { p = n % 13 + 1; }
private:
   int  p;
};

class card {
public:
   suit  s;
   pips  p;
   void  assign(int n) 
     { cd = n; s = suit(n / 13); p.assign(n); }
private:
   int  cd;       //a cd is from 0 to 51
};
