在我的C ++程序非常奇怪的错误

我已经完成的程序在插入math部分之前工作得很好。 完成math部分后，我构build了代码，并没有出现错误。 但是，当我试图debugging我的程序，我得到这个提示：“在Reciept.exe中的0x4f7ccb1a（msvcr100d.dll）未处理的exception：0xC0000005：访问冲突写入位置0x4e65ab48”。

我首先想到这是math，但是我把它删除了，再次运行这个程序，以前想要的结果是没有的。 同样的提示出现了。

你能告诉我发生了什么事吗？

这是我的代码：

• 在没有MFC的情况下从C ++运行JavaScript函数
• 如何在.NET中使用新的进度控制（如Windows文件传输所示）？
• 如何从Amazon EC2实例中找出“公共DNS名称”？
• NodeJS – 产卵function
• 将C＃应用程序从WinXP转换为7：如何使它不需要pipe理员权限？
