编译错误时出错：break 语句不在循环内或 switch case 标签'不在 switch 语句内

我无法附上整个代码，因为如果您坚持要查看整个代码，请告诉我，我会以某种方式上传它，这太错误了。

案例语法示例

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。并且您需要指定哪些变量case语句引用 usingswitch语句。如果您坚持要测试一个char*变量，那么行为将与您的预期不同，因为您将只比较指针，而不是char*数组的内容。

在您的情况下，您最好使用if, else if。
