Mac VsCode g++编译报错：不支持C++11语法解决

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

json 复制代码

{
  "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
