你用的什么编译器？这是Windows下使用Win API的程序，不要在别的环境中编译。

为什么我是这样的？

好些天没来了 帮顶！

这是C++程序，文件扩展名为.cpp，不是.c。

谢谢，但是拓展名改了之后还是会出现错误，如下：
Compiling...
Text1.cpp
C:\Documents and Settings\Administrator\桌面\Text1.cpp(14) : error C2065: 'GetConsoleWindow' : undeclared identifier
C:\Documents and Settings\Administrator\桌面\Text1.cpp(70) : error C2065: '_countof' : undeclared identifier
C:\Documents and Settings\Administrator\桌面\Text1.cpp(77) : error C2065: '_getwch' : undeclared identifier
Error executing cl.exe.

Text1.obj - 3 error(s), 0 warning(s)
求指教。

缺了Windows.h头。
第1个（取cmd窗口的句柄）是Windows API的库函数，用Windows.h，这个程序绝大多数的函数都是这个头中的函数
第2个（统计数组的元素数目）是在stdlib.h头中的，Windows.h自动包含它，如果没有，就自己#include <stdlib.h>
第3个（从键盘接收一个按键，其值是4字节的整数，即宽字符版本_getch()，对应K_ENTER的值即知）是在conio.h头中的，用于控制台键盘和屏幕IO

小声一下，这里用vc6的人还是比较多，T版的程序能否照顾一下这些人呢？

我没用过VC6，不知道哪些函数它没有。

如果C++也有　　ｔｕｂｏｃ的＜ｇｒａｐｈｉｃｓ．ｈ＞就好了　　这样交作业很容易　　　爱╮（╯▽╰）╭

可以把控制台的代码好好解析一下吗？方便我们学习
