Question

Since x_str,y_str are local, I am not getting the correct output in this function. (Illegal chars are printed in the place of x_str and y_str)
I dont want to add 2 more member variables x_str,y_str to my class.

Hence what could be the replacement of this function to get correct output.

string Pos::getPosReport(){
        string x_str;
        x_str = x;
        string y_str;
        y_str = y;
       return string("(" + x_str + "," + y_str + ")" );
    }

EDIT:

class Pos {
    int x;
    int y;
public:
    Pos();
    Pos(Pos const&);
    Pos(int,int);

    Pos&     operator=(Pos const&);
    bool    operator==(Pos const&);
    bool    operator!=(Pos const&);

    void    setPos(Pos const&);
    void    setPos(int,int);

    void    setx(int);
    void    sety(int);

    int    getx() const ;
    int    gety() const ;

    string getPosReport();

    virtual ~Pos();
};

Answer 1

std::stringstream ss;
ss << "(" << x << "," << y << ")";
return ss; 

(this is the whole function body).
