我正在学习c++，我使用的是Mac版的Visual Studio代码，我使用Code Runner来运行我的程序，我的问题是，当我使用c++11中的“auto”来声明变量时，Visual Studio代码会给我这样的警告，但如果我尝试在Xcode或Eclipse上运行它，它不会：

warning: 'auto' type specifier is a C++11 extension [-Wc++11-extensions]
for(auto y: nstrVec)

这是必要时的程序：

#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;
}

这是c_cpp_属性. json文件：
