Question

我已经在这个项目上工作了30多个小时，现在我几乎和第一次开始时一样迷失了。我终于能够打印出7排3张牌，但我的程序仍有一些问题。

我需要将卡片放在“of”
当我调用我的PrintDeck（）函数时，它应该打印出牌组中的所有牌，但它不会。
我不能为我的生活找出如何拿起卡片列以便做到这一点，如果用户选择第1列我应该第二次拿起它然后处理它们再次分为7行3列。然后让他们再次选择他们的卡片并做同样的事情。

非常感谢您提供的任何帮助。我知道有些代码不是很漂亮，但为了让我获得荣誉，它必须是分配方式：/非常感谢你的帮助。

说明：如果链接有效，这是一个文档----＆gt; instructions doc 计划要求：

您的程序必须使用以下技术生成自己的随机卡片组：

为每张卡生成一个随机整数
显示每张卡片的字符串值（“Ace of Diamonds”）
使用rand（）函数生成整数卡值
使用srand（time（0））命令（程序开头只有一次），一旦程序经过测试并正常运行，就可以生成一个真正随机的套牌。

每个值必须转换为上例中的格式。每当你的程序显示卡片时，他们必须按照上面的单词“of”排列您的程序必须逐行处理这些卡并按列进行拾取（3次以使其正常工作）你的节目必须要求玩家他/她想要在播放前打印出整个牌组。每张卡必须按照上述格式打印出来你的节目必须询问玩家他/她是否想再次玩，并继续玩玩家想要的次数该程序必须向玩家询问他/她的名字，并在整个游戏过程中按名称引用玩家您的程序代码必须使用函数进行逻辑组织。您还必须使用提供的启动器文件。如果您不使用启动文件，您将获得零（0）！

好的，有一些问题，所以我会一点一点地帮助你。第一种是你的印刷套牌方法，它实际上并没有印刷任何东西......你也传递了错误的东西。再看看这个方法，看看你是否可以先打印一些东西，然后再看看它为什么打印错误的东西
