to_string is not a member of std, says g++ (mingw)

Question

I am making a small vocabulary remembering program where words would would be flashed at me randomly for meanings. I want to use standard C++ library as Bjarne Stroustroup t

Answer 1

Use this function...

    #include
    template 
    std::string to_string(T value)
    {
      //create an output string stream
      std::ostringstream os ;

      //throw the value into the string stream
      os << value ;

      //convert the string stream into a string and return
      return os.str() ;
    }

    //you can also do this
    //std::string output;
    //os >> output;  //throw whats in the string stream into the string
