祖玛游戏的 C 语言实现

以下是一个简单的使用 C 语言实现的祖玛游戏代码示例，供您参考：

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

#define BALL_NUM 5     // 祖玛球颜色数
#define BALLS_PER_ROW 21  // 每行祖玛球的数量

// 定义祖玛球的颜色
enum BallColor {
    RED = 1, 
    YELLOW, 
    GREEN, 
    BLUE, 
    PURPLE
};

// 定义祖玛球的结构体
typedef struct ball {
    int color;
    struct ball* prev;
    struct ball* next;
} Ball;

// 初始化祖玛球链表
void initBalls(Ball** head, Ball** tail) {
    *head = (Ball*)malloc(sizeof(Ball));
    *tail = (Ball*)malloc(sizeof(Ball));
    (*head)->prev = NULL;
    (*head)->next = *tail;
    (*tail)->prev = *head;
    (*tail)->next = NULL;
}

// 在祖玛球链表尾部插入新球
void insertBall(Ball* tail, int color) {
    Ball* ball = (Ball*)malloc(sizeof(Ball));
    ball->color = color;
    ball->prev = tail->prev;
    ball->next = tail;
    tail->prev->next = ball;
    tail->prev = ball;
}

// 生成随机的祖玛球
int getRandBall() {
    return rand() % BALL_NUM + 1;
}

// 打印祖玛球链表
void printBalls(Ball* head) {
    Ball* p = head->next;
    while (p->next != NULL) {
        printf("%d ", p->color);
        p = p->next;
    }
    printf("\n");
}

// 删除祖玛球链表中的连续球
int removeBalls(Ball* head, Ball* tail) {
    int cnt = 0;
    Ball* p = head->next;
    Ball* q = p;
    while (p->next != NULL) {
        if (p->color == p->next->color) {
            cnt++;
        } else {
            if (cnt >= 2) {
                while (cnt--) {
                    Ball* tmp = q;
                    q = q->next;
                    q->prev = tmp->prev;
                    tmp->prev->next = q;
                    free(tmp);
                }
                head->next = q;
                p = q;
                cnt = 0;
            } else {
                q = p->next;
                cnt = 0;
                p = p->next;
            }
        }
    }
    if (cnt >= 2) {
        while (cnt--) {
            Ball* tmp = q;
            q = q->next;
            q->prev = tmp->prev;
            tmp->prev->next = q;
            free(tmp);
        }
        head->next = q;
    }
    return cnt;
}

// 插入新的祖玛球序列
void insertBalls(Ball* head, Ball* tail) {
    int cnt = 0;
    Ball* p = head->next;
    while (p->next != NULL) {
        cnt++;
        p = p->next;
    }
    while (cnt < BALLS_PER_ROW) {
        insertBall(tail, getRandBall());
        cnt++;
    }
}

// 判断是否游戏结束
int isGameOver(Ball* head, Ball* tail) {
    Ball* p = head->next;
    while (p->next != NULL) {
        if (p->color == p->next->color) {
            return 0;
        }
        p = p->next;
    }
    return 1;
}

// 主函数
int main() {
    srand(time(NULL));

    Ball* head, * tail;
    initBalls(&head, &tail);

    int score = 0;
    insertBalls(head, tail);

    while (1) {
        printf("当前得分：%d\n", score);
        printf("祖玛球序列：");
        printBalls(head);

        int index;
        printf("请选择要发射的祖玛球颜色(1-5)：");
        scanf("%d", &index);
        if (index < 1 || index > 5) {
            printf("输入错误，请重新选择！\n");
            continue;
        }

        Ball* p = tail->prev;
        while (p != head) {
            if (p->color == index) {
                break;
            }
            p = p->prev;
        }
        if (p == head) {
            printf("发射的祖玛球颜色不存在，请重新选择！\n");
            continue;
        }

        Ball* q = p;
        while (q->next != tail && q->next->color == p->color) {
            q = q->next;
        }
        Ball* newBall = (Ball*)malloc(sizeof(Ball));
        newBall->color = index;
        newBall->prev = q;
        newBall->next = q->next;
        q->next->prev = newBall;
        q->next = newBall;

        int cnt = removeBalls(head, tail);
        if (cnt > 0) {
            score += cnt;
        }
        insertBalls(head, tail);

        if (isGameOver(head, tail)) {
            printf("游戏结束！\n");
            printf("最终得分：%d\n", score);
            break;
        }
    }

    return 0;
}

上述代码实现了一个简单的祖玛游戏，包括初始化祖玛球链表、插入新球、打印祖玛球链表、删除连续球、插入新的祖玛球序列、判断是否游戏结束等功能。您可以根据需要进行修改和扩展。
