c++ integer->std::string conversion. Simple function?

Question

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.

Answer 1

Now in c++11 we have

#include <string> string s = std::to_string(123);
