'ostringstream take char value' No, that's wrong! You can use the output operator>>() for any primitive type as usual! — πάντα ῥεῖ

If you have a compiler supporting C++11, then std::to_string() is what you want.

You can make your 'homebrew' to_string() function very easy using std::stringstream:

template<typename T>
std::string to_string(T value)
{
    std::ostringstream oss;

    oss << value;
    return oss.str();
}
