How separate Array of strings into two filesM C++98 / VS2010

If I have two files myclass.h and myclass.cpp how to separate this code to declaration of class member and implementation of constructor where I need to set the values in brackets {}?

std::string predefinedArgs[] = { "Some", "Other", "Strings" };

I tried header:

class Wrapper {
    public:
        std::map<std::string,std::string> arguments;
        Wrapper(int argc, char ** argv);
    private:
        int argc; char ** argv;
        std::vector<std::string> args;
        std::string predefinedArgs[12];
        void parseArguments();
};

And .cpp:

Wrapper::Wrapper(int argc, char ** argv):
  argc(argc),
  argv(argv),
  args(argv, argv+argc)
  {
      this->predefinedArgs[] = { "Jan", "Feb", "Mar", "April", "May", "June", "July", 
    "Aug", "Sep", "Oct", "Nov", "Dec" };*/
     // this->parseArguments();
  };

which is wrapper.cpp(8): error C2059: syntax error : ']'

I searched net but I cannot find one serious example showing this. Don't you use classes? (just a rhetorical question)

Edit: Init. list also failed:

#include "wrapper.h"

Wrapper::Wrapper(int argc, char ** argv):
  argc(argc),
  argv(argv),
  args(argv, argv+argc),
  predefinedArgs({ "Jan", "Feb", "Mar", "April", "May", "June", "July", 
    "Aug", "Sep", "Oct", "Nov", "Dec" })
  {
      // this->parseArguments();
  };

wrapper.cpp(7): error C2143: syntax error : missing ')' before '{'

From the name of predefinedArgs I guess you might consider using static const member (or other solutions) and put it outside of the constructor completely.

E. g. like this:

.hpp

class Wrapper {
    // ...
    private:
        static const std::string predefinedArgs[12];
};

.cpp

const std::string Wrapper::predefinedArgs[12] = { "Jan", "Feb", "Mar", "April", "May", "June", "July", "Aug", "Sep", "Oct", "Nov", "Dec" };
