1、程序大体结构：

主要使用了链表结构

部分代码：

void InsertCard1(struct Card card) {
	PCardBase new_card = (PCardBase)malloc(sizeof(PCardBase) * 50);
	//尾插法
	//判错
	if (new_card == NULL) {
		HWND hwndInput2 = GetHWnd();
		MessageBox(hwndInput2, "分配内存失败！", "提示", MB_OK);
	}
	else {
		new_card->cards = card;
		CardHead->pre->next = new_card;
		new_card->pre = CardHead->pre;
		CardHead->pre = new_card;
		new_card->next = CardHead;
		CardHead->cards_length++; //卡数加1
	}
}
//插入用户
//void InsertUser(struct User user) {
//
//	PUserBase n = UserHead;
//	//创建新节点
//	PUserBase new_user = (PUserBase)malloc(sizeof(PUserBase) * 50);
//	//判错
//	if (new_user == NULL) {
//		HWND hwndInput2 = GetHWnd();
//		MessageBox(hwndInput2, "分配内存失败！", "提示", MB_OK);
//	}
//	else {
//		//头部插入元素
//		new_user->users = user;
//		new_user->next = n->next;
//		UserHead->next = new_user;
//
//		UserHead->user_length++; //用户数加1
//	}
//
//}
