Unable to run c++ program in vscode

[anurawat01]

I am getting this error when I am using auto keyword in my program.

warning: 'auto' type specifier is a C++11 extension [-Wc++11-extensions]

Help please ?

You need to add the flag "-std=c++11" when building, e.g. to "args" in tasks.json if you're building that way.

I am already using that but then also I am not able to run it.
Please help I have wasted my one full day for configuring it even I have reinstall everything then also.

I don't know why that isn't working. It's only a warning, so does your code compile? Does it work if you run /usr/bin/clang++ -std=c++11 etc. from the command line?

Yeah, If I do run this then it does work.
