What is the easies way to convert int to std::string?

int x,
how to convert x to std::sting type?

Code:

---

#include <sstream>

std::stringstream int_to_string;

int x = 0;

int_to_string << x;

std::cout << int_to_string.str() << std::endl;

---

thats the simplest way I know.

#include <sstream>

std::stringstream int_to_string;
int x = 0;
int_to_string << x;
std::string str(int_to_string.str());

Correct?

youre creating a new string from the string returned by the .str(). seems it should work. best way to find out is to try it

Alternatively:

Code:

---

template <class var_t>
std::string ToString(var_t data)
{
    static std::stringstream ss;
    ss << data;
    return ss.str();
}

---

If you have boost. Use lexical_cast. It basically does the same thing under the hood, but it provides a uniform interface for all of these types of conversions.

I'm not sure if that's in std::tr1 or not, but it might be.

Why is that stream static? That introduces at least two bugs right there.
