错误：在C ++ 98模式下不允许基于范围的“for”循环 [英] Error: Range-based 'for' loops are not allowed in C++98 mode

问题描述

因此，我按照此页面上的教程：
http://www.cplusplus.com / doc / tutorial / control /
但是我有麻烦做一个range / based for循环。我找到这个页面：
GNU GCC编译器更新答案说我应该打开项目和属性。但是当我尝试时，属性选项是灰色的，没有解释：
http：// imagehack.com/a/img571/4371/xd1x.png
所以..如何激活基于范围/基于循环？

So I'm following the tutorials on this page: http://www.cplusplus.com/doc/tutorial/control/ But I'm having trouble doing a range/based for loop. I found this page: GNU GCC compiler updatingThe answer there says I should open "Project" and "Properties". But when I try that, the "Properties" option is grayed out with no explanation: http://imageshack.com/a/img571/4371/xd1x.png So.. how can I activate range/based for loops?

推荐答案

将 -std = c ++ 11 标志传递给编译器。当然，GCC应该足够新鲜（> = 4.7）以支持所有这些现代标准。对于CodeBlocks 13.12：设置 - >编译器 - >选项卡编译器标志 - >选项有g ++遵循C ++ 11 ISO C ++ [-std = c ++ 11]

Pass -std=c++11 flag to the compiler. Certainly GCC should be fresh enough (>=4.7) to support all these modern standards. For CodeBlocks 13.12: Settings -> Compiler -> Tab "Compiler Flags" -> Option "Have g++ follow the C++11 ISO C++ [-std=c++11]"
