中

我无法附上整个代码，因为如果你坚持要看到整件事告诉我并且我会上传一些内容，那就太麻烦了。

案例

的示例语法

switch (variable)
{
   case 1:
      //Do stuff
      break;
   case 2:
      //Do stuff
      break;
   default:
      //Do stuff
      break;
}

请记住，通过使用switch语句，您只能处理整数变量。您需要指定哪个变量case语句引用使用switch语句。如果你坚持要测试char*变量，那么行为将与你期望的不同，因为你只是比较指针，而不是char*数组的内容。

在您的情况下，您最好使用if，else if。
