c++ - Visual C++ 和 *nix 环境中的编译差异

在 *nix 环境和 MS Visual C++ 环境下编译项目有区别吗?例如,Visual C++中有一个“stdafx.h”文件。

我问的原因是我提交了一段用 g++ 编译的代码到 refactormycode.com .然后在重构之后,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,并将自动生成的 .cpp 替换为重构代码。我在这里做错了什么吗?

这是我得到的编译器错误:

最佳答案

在重构代码中添加以下 header ,

#include <iostream>
#include <limits>
#include <map>
#include <list>
#include <queue>
