如何为 C++ 14/C ++17 设置 VS 代码

问题描述

我试图从工作区运行一个 .cpp 文件，但给了我这个关于不添加 c++11/higher 标志的错误，但我已将它们添加到 task.json

I tried to run a .cpp file from workspace but giving me this error about not adding c++11/higher flags but I have added them in task.json

推荐答案

我添加了代码运行器并将其添加到 settings.json 似乎对我有用 :D

I added code runner and added this in settings.json Seems to work for me :D

"code-runner.executorMap": {
    "cpp": "cd $dir && g++ -std=c++17 $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt",
},
