扑克牌游戏c语言课程设计

以下是一个简单的扑克牌游戏的C语言课程设计，实现了21点的基本规则：

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

#define MAX_CARD_NUM 52
#define MAX_PLAYER_CARD_NUM 5

// 扑克牌结构体
typedef struct {
    char suit; // 花色
    char rank; // 点数
} Card;

// 玩家结构体
typedef struct {
    Card cards[MAX_PLAYER_CARD_NUM]; // 手牌
    int card_num; // 手牌数量
    int point; // 点数
} Player;

// 初始化扑克牌
void init_cards(Card *cards) {
    char suits[4] = {'S', 'H', 'D', 'C'}; // 花色
    char ranks[13] = {'A', '2', '3', '4', '5', '6', '7', '8', '9', 'X', 'J', 'Q', 'K'}; // 点数
    int i, j, k = 0;
    for (i = 0; i < 4; i++) {

// 洗牌
