BlackJack游戏的一般alogirthm是什么？ 我正在用c ++编写一个，如果语句破坏整个事情，最终会有太多的错误。
该项目是一个win32 GUI应用程序，我发布消息循环以及检查游戏状态的程序部分 发布完整的代码将使它变得非常庞大，所以这里是所有文件的链接： Full Source Code

答案 0 :(得分：2)
作为第一步：我可能不会混合游戏逻辑和GUI逻辑......将它们分成不同的模块。
如果你只有两名球员，你只需要一个布尔来决定赢得哪一名。你不需要两个玩家Bust和Won变量。
答案 1 :(得分：1)
Google搜索在BlackJack算法上显示this PDF paper。我敢肯定，如果您使用Google进行更多研究，您也可以找到它。
要弄清楚如何计算游戏需要完成的实际步骤，在纸上计算游戏的不同步骤，然后决定如何创建代表游戏部分和功能的类。用于执行游戏不同步骤的类。'
这可能是一个迭代的事情，你经历它，然后创建一些类，函数等，现在你可以回去看看你做了什么是有意义的，改进设计等。
也许还会玩游戏，看看做了什么，如何将其翻译成代码。
答案 2 :(得分：0)
我修改了程序处理邮件的方式，并将其作为单独的答案发布。 由于轻微的打嗝，它仍然被打破，但我认为一般的想法是坚实的。评论将不胜感激
