I had some C style code that essentially had

const char * choices[] = {"Choice A", "Choice B", "Choice C", "Choice D"};

Now this is obviously a problem in a class framework as it can not be
initialized in the class definition.

So I tried some variations so I didn't have to alter the internal code
that used the array. Someone told me to make it a static array, but
something happened which I didn't expect. I tried

screens.h

class menu_window
{
public:

/* ==================== LIFECYCLE ======================================= */
menu_window (); /* constructor */
menu_window (int height, int width, int row, int col);
menu_window ( const menu_window &other ); /* copy constructor */
~menu_window (); /* destructor */

WINDOW *menu_win;
static char const *choices[5];
int height;
int width;
....

}


screens.cpp

Screens::menu_window::menu_window (int pheight, int pwidth, int prow, int pcol): height(pheight), width(pwidth), highlight(1), choice(0) , n_choices(sizeof(choices)/ sizeof(choices[0])) {
row_(prow);
col_(pcol);
choices[0] = "Add a question ";
choices[1] = "Start the Quiz ";
choices[2] = "c ";
choices[3] = "d ";
choices[4] = "Exit ";
menu_win = newwin(height, width, row_(), col_() );
keypad(menu_win, TRUE);
mvprintw(0,0, "Use arrow keys to go up and down, Press enter to select choice");
refresh();
print_menu(menu_win, highlight);


} /* constructor */



and this failed as a static. When I removed static, it works fine. Why?
