Problem: I have an integer; this integer needs to be converted to a stl::string type. In the past, I've used stringstream to do a conversion, and that's just kind of cumbersome. I know the C way is to do a sprintf , but I'd much rather do a C++ method that is typesafe(er). Is there a better way to do this? Here is the stringstream approach I have used in the past: std::string intToString(int i) { std::stringstream ss; std::string s; ss << i; s = ss.str(); return s; } Of course, this could be rewritten as so: template<class T> std::string t_to_string(T i) { std::stringstream ss; std::string s; ss << i; s = ss.str(); return s; } However, I have the notion that this is a fairly 'heavy-weight' implementation. Zan noted that the invocation is pretty nice, however: std::string s = t_to_string(my_integer); At any rate, a nicer way would be... nice.
