再次回答C中的另一个问题。 我的switch语句有些问题。我的程序正在编译并运行它甚至将正确的值存储在正确的变量中并运行switch语句，因为在打印输出特定输出时它应该是EXCEPT。请记住我正在努力学习，而且我的知识非常基础。我很感谢你在这个迷人的社区中的所有帮助，并且我要求你的回答，如果有的话可以帮助我了解更多！
没有进一步的麻烦，这里出现了一段编码文字！

答案 0 :(得分：0)
变量memory, hd, monitor等声明为整数，但您的switch语句使用类型char。只需删除单引号...
case '1': // this is a char
case 1: // this is an integer
