Addition of stringstream & string

[forstudy3]

I am performing addition on strings but not getting desired result .Kindly help me with proper solution-

std::stringstream out;
string addstr ="Good Name";
string name = "rahul;
out << "Your Name " << name;

out.str() = out.str() + addstr; //This operation is returing = "Your Name rahul" but I need 'addstr' to be added as well 

[Bazzy]

what about out << addstr ?

I believe stringstream does not overload operator +. (http://www.cplusplus.com/reference/iostream/stringstream/)

Follow Bazzy solution.

out << "Your Name " << name << addstr;
