环境;win7 32,vs2013

代码：

#include <iostream>using namespace std;namespace MYSPACE{enum class choice{rock,paper,scissors};}typedef MYSPACE::choice Mchoice;int main(){Mchoice c = Mchoice::rock;return 0;}

报错：

原因：vs2013使用了vs2010库，而vs2010不支持c++0x新增的强类型enum class

解决：在vs2013项目属性里,General->Platform Toolset,选择Visual Studio 2013 - Windows XP (v120_xp)或者Visual Studio 2013
