纸牌游戏 - 我怎样才能做出这样的声明？

Question

我正在尝试做一个纸牌游戏（用户对电脑），首先获得 7.5 分的人获胜。为此，我创建了一套有 4 套套装，每套 10 张牌的套牌。卡片从 1 到 10，卡片的价值从 1 到 7，他们看重他们拥有的数字。卡片 8,9 和 10 值 0.5 分。

在有人在这里帮助我card game - what to put between the square brackets [ ]? 之后，我对我的代码进行了一些更改，现在我得到了如下所示。问题是我不知道如何发表声明说：如果所有卡片都已被选中（即数组'draw'全部设置为1），游戏结束。有人可以帮我吗？

#include <stdio.h>

牌组可以洗牌。然后遍历卡片组并递增n。
