扑克牌发牌程序。给四个玩家发牌(不含大小王)，要求每次发的牌都不一样。

 分析:

　　 52张牌采用1~52代表，其中黑桃对应1~13，红桃对应14~26，梅花对应27~39，方块对应40~52。例如: 28 是梅花2, 29 是梅花3。将52张牌(号)依次随机放入数组Deck中。方法是随机产生在数组中放置的位置 r (下标号)，如果该位置已有牌(Deck[r] != 0), 则重新生成新的位置r，直到该位置无牌。 

 

#include <iostream>
#include<cstdlib>
#include<ctime>
using namespace std;

int main() {
    int card, r, Deck[52];
    char pok_C[4][7] = {"黑桃","红桃","梅花","方块"};
    char pok_N[13][3] = 
    {"A","2","3","4","5","6","7","8","9","10","J","Q","K"};
    srand((unsigned)time (0));       //随机种子
    
    for(int i=0; i<=52; i++){
        Deck[i] = 0;
    }
    for(card=1; card<=52; card++){
        r = rand() % 52;
        while(Deck[r] != 0){
            r = rand() % 52;
        }    
        Deck[r] = card;
    }
    
    cout<<"play1\t play2\t play3\t play4\n";
    cout<<"-----------------------------------------\n";
    
    for(int i=0; i<52; i++){
        cout<<pok_C[(Deck[i]-1)/13]<<pok_N[(Deck[i]-1)/13]<<'\t';
        if(i%4 == 3){       //从0开始
            cout<<endl;
        }
    }

    return 0;                                                 
}
