[开源]C++实现控制台随机迷宫

我全程使用TCHAR系列函数，亲测可以不改动代码兼容Unicode/ANSI开发环境，功能正常。大概有100行代码是来自网络的，我也做了改动，侵权请联系删除。本文作者szx0427，只发布于CSDN与博客园

这个代码不能算是完美，还是会有轻微的闪屏现象，懒得再加双缓存了，大家可以自行修改。这里用的是SetConsoleCursorPosition函数和cls刷新屏幕。

好了，上代码！VS2015编译通过无警告。其他版本应该也没问题

这是C风格的代码。因为用到了内联函数等C特性，可能不能直接兼容C语言环境，但是稍作改动即可完美兼容。（ps：至少大家不用为字符集设置发愁了 XD）
