how to in initialize a stringstream

Hi All,
hope someone can tell me how to initialize a stingstream. I have some code I use to send data over the network, this uses stringstream to convert numbers to a stream. It works great. However I've decided to clean my code up with Cppchecker. This is giving me the following error
Uninitialized variable: ss

my code is

Code:

template <class T> std::string to_string(const T& t)

{

    std::stringstream ss ;

    ss << t;

    return ss.str();

}

how can I set this line up std::stringstream ss = ........;

Thanks in advance!

I don't know C++, but I'd try this:

Code:

template <class T> std::string to_string(const T& t)

{

    std::stringstream ss();

    ss << t;

    return ss.str();

}

Thanks but that just gives a load of errors.

Next try:

Code:

#include <string>

#include <sstream>



template <class T> std::string to_string(const T& t)

{

    std::stringstream ss = 0;

    ss << t;

    return ss.str();

}

(Of course I cannot tell what your code does, or if it does anything at all.)

You could try ostringstream to limit it to output-only.

I think

Code:

std::stringstream ss(std::ios_base::out);

would work. Although really this is a flaw in CppChecker, because the variable is in fact initialized regardless.

Thanks all. I'll give the last one a try why I'm back at my pc, I think that might work. I have noticed that cppchecker which seems very good, seems to give warnings about things that for the life of me I don't think are wrong. But still I feel it would be better if everything has passed
