DevC++如何支持C++11

今天在写代码时用$unordered\_map$时出现了的问题，报了以下错误。

#error This file requires compiler and library support for the \
ISO C++ 2011 standard. This support is currently experimental, and must be \
enabled with the -std=c++11 or -std=gnu++11 compiler options.

从网上得知是DevC++没支持C++11
解决方法也很简单：
1.点击工具

2.点击Compiler Options

3.-std=c++11并添加
4.确认即可
