      printw("\n\n\nThe character entered was a '%c'.\n", ch);
      refresh();
      endwin();
   }

The output from this program follows. The first refresh sends the addstr character string from stdscr to the terminal: 

   Press any character:  []
   
   

Now assume that a w is typed at the keyboard. getch accepts the character and assigns it to ch. Finally, the second refresh is called and the screen appears as follows: 

   Press any character:  w
   
   
   The character entered was a 'w'.
