I am in the process of learning c++ and I'm using visual studio code for Mac. I use Code Runner to run my program. My problem is that when I use something from c++11 like "auto" for variable declaration, visual studio code gives me a warning like this, but if I try running it on Xcode or Eclipse it doesn't:

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

for(auto y: nstrVec)

This is the program if it's necessary:

#include <iostream>

#include <cstdlib>

#include <string>

#include <vector>

#include <numeric>

#include <sstream>



int main(){



std::vector<std::string> nstrVec(10);



std::string str("I'm a string");

nstrVec[0] = str;



std::cout << str.at(0) << "n";

std::cout << str.front() << " " << str.back() << "n";

std::cout << "Length " << str.length() << "n";

// copies all characters after the fourth 

std::string str2(str, 4);



for(auto y: nstrVec)

    if(y != "")

        std::cout << y << "n";



return 0;

}

And this is the c_cpp_proprerties.json file:

{

"configurations": [

    {

        "name": "Mac",

        "includePath": [

            "${workspaceFolder}/**",

                 "/System/Library/Frameworks/Kernel.framework/Versions/A/Headers"

        ],

        "defines": ,

        "macFrameworkPath": [

            "/System/Library/Frameworks",

            "/Library/Frameworks"

        ],

        "compilerPath": "/usr/bin/clang",

        "cStandard": "c11",

        "cppStandard": "c++17",

        "intelliSenseMode": "clang-x64"

    }

],

"version": 4

}

For everyone who comes to this question to find a quick answer (like I did):

The following compiler command should compile your program main.cpp with the latest C++ standard (c++17) and should get rid of warning messages like the one described above:

g++ -std=c++17 -g main.cpp -o main

It is mentioned multiple times in the comments, but I think this question should have a regular answer.

I had the same problem, but solved it using set vscode-user-settings <>

"clang.cxxflags": ["-std=c++14"]
