广州做网站建设/互联网怎么赚钱

编译运行时报错：
[Running] cd “/Users/yiran/Documents/vs_projects/c++/” && g++ 1116.cpp -o 1116 && "/Users/yiran/Documents/vs_projects/c++/"1116
1116.cpp:28:22: warning: range-based for loop is a C++11 extension [-Wc++11-extensions]

报错截图：

解决方案：
在.vscode/settings.json中配置如下，目的是在编译命令中添加编译选项-std=c++11

{"C_Cpp.errorSquiggles": "enabled","files.associations": {"vector": "cpp"},// 添加如下配置，对应文件路径替换成对应自己的路径"code-runner.executorMap": {"cpp": "cd '/Users/yiran/Documents/vs_projects/c++/' && g++ -std=c++11 $fullFileName -o $fileNameWithoutExt && ./$fileNameWithoutExt"}}

如果不生效，也可以在.vscode/tasks.json中添加如下配置，在编译命令中添加编译选项-std=c++11
