一个小小的结构体问题？？——改来改去都跟书的的例题一样了还是不行

#include <iostream>
using namespace std;
struct BitCards
{
    unsigned face : 4;
    unsigned suit : 2;
    unsigned color :1;
   
};//定义一张牌

class DeckOfCards
{
public:
    DecdOfCards();/*初始化一副牌*/
    void shuffle();//洗牌函数
    void deal();/*发牌小函数*/
private:
    BitCards cards[52];/*定义52张牌*/

};


DeckOfCards::DecdOfCards()
 {
     for( int i=0;i<52;i++)
     {
         cards[i].face=i%13;
        cards[i].suit=i/13;
         cards[i].color=i/26;
        cout<<"kan"<<cards[i].face;
     }
 }

 void DeckOfCards::shuffle()
 {
     for(int i=0; i<52; i++)
     {
         int j=rand()%52;
        BitCards temp;
         temp=cards[j];
        cards[j]=cards[i];
         cards[i]=temp;
     }
 }

void DeckOfCards::deal()
{
    for(int i=0;i<52;i++)
    {
        cout<<"\t\t"<<cards[i].face<<" of "
            <<cards[i].suit<<"\t\t";
        if(i%2==0)
            cout<<endl;
    }
}

void main()
{
    DeckOfCards test;
//     test.shuffle();
//     test.deal();
}
