Case语句不执行

Question

这对我来说是一个越来越大的恼怒的来源，当我按下相应的按钮(它们在上面初始化)，它们实际上没有执行，我被卡在菜单里。

我肯定这太简单了，我只是没看到而已。

Answer 1

choice = askForChar(POKER_MENU, GO_BACK, FIVE_CARD);

应该是

poker_choice = askForChar(POKER_MENU, GO_BACK, FIVE_CARD);

Answer 2

既然你说这是在一个方法里，

这里几乎没有什么东西需要检查；

• 一旦进入该方法，只需打印poker_choice并查看您的值是否被正确传递。
• 检查德克萨斯州FIVE_CARD的所有情况是否都声明为相同数据类型的常量。

Answer 3

您的错误似乎出现在这条线上：

choice = askForChar(POKER_MENU, GO_BACK, FIVE_CARD);

在您的poker_choice中测试switch，但是将值分配给choice。

它应该是：

   poker_choice = askForChar(POKER_MENU, GO_BACK, FIVE_CARD);
// ^^^^^^

   switch(poker_choice)
   // ...
