c语言程序设计21点扑克牌,C语言程序设计-21点扑克牌游戏.pdf

很抱歉，我无法提供您所需的pdf文件。但是，我可以为您提供一个简单的21点扑克牌游戏的C语言程序示例，您可以参考它来编写自己的程序。

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

int main()
{
    int player, dealer, player_sum, dealer_sum;
    char choice;

    srand((unsigned)time(NULL)); // 初始化随机数种子

    printf("Welcome to 21-point blackjack game!\n\n");

    // 玩家和庄家各发两张牌
    player = rand() % 10 + 1;
    dealer = rand() % 10 + 1;
    printf("Your first card is %d.\n", player);
    printf("Dealer's first card is %d.\n", dealer);

    player += rand() % 10 + 1;
    dealer += rand() % 10 + 1;
    printf("Your second card is %d.\n", player);
    printf("Dealer's second card is hidden.\n");

    // 计算点数
    player_sum = player;
    dealer_sum = dealer;

    // 玩家回合
    do {
        printf("\nDo you want to hit (h) or stand (s)? ");
        scanf(" %c", &choice);

        if (choice == 'h') {
            player += rand() % 10 + 1;
            player_sum += player;
            printf("Your new card is %d.\n", player);

            if (player_sum > 21) {
                printf("Busted! You lose.\n");
                return 0;
            }
        }
    } while (choice == 'h');

    // 庄家回合
    printf("\nDealer's turn.\n");
    printf("Dealer's second card is %d.\n", dealer);

    while (dealer_sum < 17) {
        dealer += rand() % 10 + 1;
        dealer_sum += dealer;
        printf("Dealer's new card is %d.\n", dealer);

        if (dealer_sum > 21) {
            printf("Dealer busted! You win.\n");
            return 0;
        }
    }

    // 比较点数
    printf("\nYour total is %d.\n", player_sum);
    printf("Dealer's total is %d.\n", dealer_sum);

    if (player_sum > dealer_sum) {
        printf("You win!\n");
    } else if (player_sum < dealer_sum) {
        printf("You lose.\n");
    } else {
        printf("It's a tie.\n");
    }

    return 0;
}

这个程序使用随机数生成玩家和庄家的牌，在玩家回合中，玩家可以选择是否要继续要牌，直到选择停牌或者点数超过21点为止。在庄家回合中，庄家会一直要牌直到点数大于等于17点为止。最后比较点数大小，判断胜负。

请注意，这只是一个简单的示例程序，您可以根据自己的需求进行修改和优化。
