用c++写一个21点游戏

好的，以下是一个简单的用 C 语言编写的 21 点游戏：

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

int main() {
int player_score = 0, dealer_score = 0;
char choice;

srand(time(NULL)); // 初始化随机数生成器

// 发两张牌给玩家和庄家
player_score += rand() % 10 + 1;
player_score += rand() % 10 + 1;
dealer_score += rand() % 10 + 1;
dealer_score += rand() % 10 + 1;

printf("你的牌是：%d\n", player_score);
printf("庄家的牌是：%d\n", dealer_score);

// 玩家决定是否要继续要牌
while (player_score < 21) {
printf("是否要牌？(y/n) ");
scanf(" %c", &choice);

if (choice == 'y') {
player_score += rand() % 10 + 1;
printf("你的牌是：%d\n", player_score);
} else {
break;
}
}

// 判断玩家是否爆牌
if (player_score > 21) {
printf("你爆牌了！\n");
return 0;
}

// 庄家决定是否要继续要牌
while (dealer_score < 17) {
dealer_score += rand() % 10 + 1;
printf("庄家的牌是：%d\n", dealer_score);
}

// 判断庄家是否爆牌
if (dealer_score > 21) {
printf("庄家爆牌了！\n");
return 0;
}

// 比较双方点数大小
if (player_score > dealer_score) {
printf("你赢了！\n");
} else if (player_score < dealer_score) {
printf("庄家赢了！\n");
} else {
printf("平局！\n");
}

return 0;
}

希望这个程序能够帮到你！
