1.模擬發牌程序

通過寫兩個函數模塊來編寫洗牌程序和打印的發牌程序

2.編寫洗牌程序

void shuffle(char cards[][10],int n){
    int i=54;
    char ca,cb,ct[10];
    srand((unsigned)time(NULL));
    
    while(i--){
        ca=rand()%54;
        cb=rand()%54;
        
        strcpy(ct,cards[ca]);
        strcpy(cards[ca],cards[cb]);
        strcpy(cards[cb],ct);        
    }
        
}

3.編寫打印的發牌程序

void printCard(char cards[][10],int n){
    int i,rn=0;
    printf("第一個人:\n");
    for(i=0;i<17;i++){
        if(rn%5==0)
            printf("\n");
        rn++;
        printf("%s      ",cards[i]);        
    }
    printf("\n\n第二個人:\n");
    rn=0;
    for(i=17;i<33;i++){
        if(rn%5==0)
            printf("\n");
        rn++;
        printf("%s      ",cards[i]);        
    }
    printf("\n\n第三個人:\n");
    rn=0;
    for(i=33;i<50;i++){
        if(rn%5==0)
            printf("\n");
        rn++;    
        printf("%s      ",cards[i]);    
    }
    printf("\n\n底牌:\n");
    for(i=51;i<54;i++){
        printf("%s      ",cards[i]);        
    }
    printf("\n");
    getchar();
}

4.在主函數預定義和調用

main(){
    system("color 0f");
    char cards[][10]={
    "紅桃 2","紅桃 3","紅桃 4","紅桃 5","紅桃 6","紅桃 7","紅桃 8","紅桃 9","紅桃 10","紅桃 J","紅桃 Q","紅桃 K","紅桃 A",
    "方塊 2","方塊 3","方塊 4","方塊 5","方塊 6","方塊 7","方塊 8","方塊 9","方塊 10","方塊 J","方塊 Q","方塊 K","方塊 A",
    "梅花 2","梅花 3","梅花 4","梅花 5","梅花 6","梅花 7","梅花 8","梅花 9","梅花 10","梅花 J","梅花 Q","梅花 K","梅花 A",        
    "黑桃 2","黑桃 3","黑桃 4","黑桃 5","黑桃 6","黑桃 7","黑桃 8","黑桃 9","黑桃 10","黑桃 J","黑桃 Q","黑桃 K","黑桃 A",
    "大王","小王" 
    };
    int n = 54;
 
    shuffle(cards,n);
    printCard( cards, n);
        
return 0;
}

5.最終程序

#include<stdio.h>
#include<string.h>
#include<stdlib.h> 
#include<time.h>
void shuffle(char cards[][10],int n);
void printCard(char cards[][10],int n);

main(){
    system("color 0f");
    char cards[][10]={
    "紅桃 2","紅桃 3","紅桃 4","紅桃 5","紅桃 6","紅桃 7","紅桃 8","紅桃 9","紅桃 10","紅桃 J","紅桃 Q","紅桃 K","紅桃 A",
    "方塊 2","方塊 3","方塊 4","方塊 5","方塊 6","方塊 7","方塊 8","方塊 9","方塊 10","方塊 J","方塊 Q","方塊 K","方塊 A",
    "梅花 2","梅花 3","梅花 4","梅花 5","梅花 6","梅花 7","梅花 8","梅花 9","梅花 10","梅花 J","梅花 Q","梅花 K","梅花 A",        
    "黑桃 2","黑桃 3","黑桃 4","黑桃 5","黑桃 6","黑桃 7","黑桃 8","黑桃 9","黑桃 10","黑桃 J","黑桃 Q","黑桃 K","黑桃 A",
    "大王","小王" 
    };
    int n = 54;
 
    shuffle(cards,n);
    printCard( cards, n);
        
return 0;
}

void shuffle(char cards[][10],int n){
    int i=54;
    char ca,cb,ct[10];
    srand((unsigned)time(NULL));
    
    while(i--){
        ca=rand()%54;
        cb=rand()%54;
        
        strcpy(ct,cards[ca]);
        strcpy(cards[ca],cards[cb]);
        strcpy(cards[cb],ct);        
    }
        
}

void printCard(char cards[][10],int n){
    int i,rn=0;
    printf("第一個人:\n");
    for(i=0;i<17;i++){
        if(rn%5==0)
            printf("\n");
        rn++;
        printf("%s      ",cards[i]);        
    }
    printf("\n\n第二個人:\n");
    rn=0;
    for(i=17;i<33;i++){
        if(rn%5==0)
            printf("\n");
        rn++;
        printf("%s      ",cards[i]);        
    }
    printf("\n\n第三個人:\n");
    rn=0;
    for(i=33;i<50;i++){
        if(rn%5==0)
            printf("\n");
        rn++;    
        printf("%s      ",cards[i]);    
    }
    printf("\n\n底牌:\n");
    for(i=51;i<54;i++){
        printf("%s      ",cards[i]);        
    }
    printf("\n");
    getchar();
}
