哦，那我百度一下fgetc的用法去

小哥，我又想到个问题，如果我突然打着字想退出，那不是按esc退出吗，但是这个怎么实现啊，esc键不是普通的字符啊？？？

在两位大哥的帮助下，我终于实现我的课题，哈哈，可惜还有个问题，怎么按esc键退出，并且在打字的时候按回车键不让它换行

不大是我想像中的啊，我想的是可以直接停止，然后得到结果，就像跳出循环一样，或者在子菜单中返回，在主菜单中退出

不要这样说嘛，我本来也是什么都不知道，还是在两位大神的帮助下学了很多

恩恩，我改成goto了，但是好像跳不回主函数啊？？？

那键值怎么回事？是直接宏定义，然后就可以使用了？？？

好吧，大神晚安，我再改改，网上说有throw和setjmp，我试试吧

乖乖，那不是就可以定义什么帮助啦，退出啦，什么的啊，好神奇啊

神奇了，昨天还可以退出，今天就退不出去了呢啊，按esc就出现“/”符号，为什么？？？
