integer to string conversion

[wli]

Hi,

How to convert an integer to string in order to use the result as the name of a cMessage, e.g. cMessage *m; m->setName()  I try to use an integer as the name of message m but didn't figure out how to convert the integer into a suitable string type. It seemed that the C function for this purpose atoi() can't be found. I appreciate your help, thanks.

Got error message error: ‘to_string’ is not a member of ‘std’. Do I need to specify the C++ version to solve the error, if so how should it be specified in OMNET++ or are there other alternatives. Thanks.

Have you included the header?

#include <string>     // std::string, std::to_string

[wli]

Yes I did.

Strange, I can compile without problems

 

            std::string str;

            for (int i = 0; i < numQueues; i++)

            {

                str = "wlanDataQueue" + std::to_string(i);

                dataQueue[i].setName(str.c_str());

Hi, is to_string() restricted to C++11? The string header file I am using has this indication  'ISO C++ 14882: 21  Strings library', is it an older version? Also I did a search of to_string() but found matches only in file printers.py in the inet folder.

I suppose that you are working in Windows with an old version of omnet, there is a problem with to_string in mingw with old versions

I find that sprintf() works as in http://stackoverflow.com/questions/9655202/how-to-convert-integer-to-string-in-c
