在 *nix 环境和 MS Visual C++ 环境中编译项目有区别吗？ 例如，Visual C++中有一个“stdafx.h”文件。
我问的原因是我向refactormycode.com提交了一段用g++编译的代码。 。然后在它进行重构之后，它似乎包含一个“stdafx.h”，所以我想我会下载 Visual C++ 2008 Express，但我似乎无法构建它。
我正在做的是创建一个新项目>创建一个Win32控制台应用程序，并用重构的代码替换自动生成的.cpp。我在这里做错了什么吗？
这是我遇到的编译器错误:

最佳答案
在重构的代码中添加以下 header ，
#include <iostream>
#include <limits>
#include <map>
#include <list>
#include <queue>
