我有一个 AA TREE c++ 实现源代码，我需要将该代码放入 Win32 c++ [关闭]

Question

我有一个任务要真正应用 AA 树。目前我只有控制台应用程序格式，无法转换为 win32 项目。我在visual studio 2015工作。老师没有给我们带来任何学习的内容，只是告诉我们去做。请你帮帮我好吗？这是控制台应用程序的代码：

要将您的 C++ 代码转换为 Visual C++（Windows 环境），您只需将所有 std:char 和 std:string 更改为 std:wchar 和 std::wstring ，因为 Windows 使用Unicode 中文本的宽（'w'）格式，即每个字符可以有超过 1 个字节。

在所有其他方面，您的代码与 Windows 和 Windows api 无关 - 您不包含任何特定于平台的库或标头。
