新手，分少。网上看教程写的代码，总是编译错误

执行 cl.exe 时出错.

追问

非常感谢，但是执行的时候还是有一个问题
***.obj : error LNK2001: unresolved external symbol _bioskey
Debug/***.exe : fatal error LNK1120: 1 unresolved externals
执行 link.exe 时出错.
还望高手指教啊

/*编译完全通过，但是bioskey(0)需要TC支持，我是vc，所以无法运行。这个是那个什么老鼠迷宫的么？*/
恩，就是我开始说的那么问题，你需要用tc才能运行。报错的error就是没有bioskey(0)的定义，与你编译环境有关

Answer 2

应该是中间一些大括号什么的少写了，看看下面这样行不行
#include <stdio.h>
#include <bios.h>
int x=10, y=10;

0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,

非常感谢，但虽然编译通过了，但执行的时候还是有一个错误，看了半天，很痛苦。非常感谢你这么快的回答。

Answer 3

不要我们帮你找出错误，要学会自己看错误提示，问题都不大，不是丢了分号就是多了逗号，写程序时一定要仔细一点，否则等回头再去找错误就会麻烦了！

Answer 4

tell函数少了一个大括号
