测试的时候 错误是这样的  。求具体改法。我初学 麻烦说浅显点。
12.cpp
c:\users\chenxuewei\appdata\local\temp\rar$ex06.840\vc6\myprojects\1\12.cpp(681) : fatal error C1010: unexpected end of file while looking for precompiled header directive
Generating Code...

你这个是下载人家的代码，还是自己写的？你用什么编译？

晕死，这么长

自己先运行一下程序 然后试着挑错 太大了 看都雷人

分段吧你，编程的核心思想是分成各个小段再链接起来。这样在纠错上也容易点，根据算法分段 一段一段的试试

这好像是叫分治吧

代码有点长，没有具体看，但是错误类型是 fatal error C1010，
解决方法：
1、如果发生错误的文件是由其他的C代码文件添加进入当前工程而引起的，则Alt+F7进入当前工程的 Settings，选择C/C++选项卡，从Category组合框中选中Precompiled Headers，选择Not Using Precompiled headers。确定。

2、在文件开头添加:
#include "stdafx.h"

  对预编译头文件说明如下：   
   
  所谓头文件预编译，就是把一个工程(Project)中使用的一些MFC标准头文件(如Windows.H、Afxwin.H)预先编译，以后该工程编译时，不再编译这部分头文件，仅仅使用预编译的结果。这样可以加快编译速度，节省时间。  
   
  预编译头文件通过编译stdafx.cpp生成，以工程名命名，由于预编译的头文件的后缀是“pch”，所以编译结果文件是projectname.pch。   
   
  编译器通过一个头文件stdafx.h来使用预编译头文件。stdafx.h这个头文件名是可以在project的编译设置里指定的。编译器认为，所有在指令#include   "stdafx.h"前的代码都是预编译的，它跳过#include   "stdafx.   h"指令，使用projectname.pch编译这条指令之后的所有代码。   
   
  因此，所有的CPP实现文件第一条语句都是：#include   "stdafx.h"。

7楼正解，新手还是不要用vc的好
