ncurses refresh()

i have read in one of links, there its documented
Quote:
The job of printw is to update a few flags and data structures and write the data to a buffer corresponding to stdscr. In order to show it on the screen, we need to call refresh() and tell the curses system to dump the contents on the screen.
but i am using following code

Code:
 int main ()
 {
     char ch;
     initscr();
     printw("Enter a char :");
     ch=getch();
     printw("You Entered '%c' ",ch);
     getch();
     endwin();
     return 0;
}

the code does not have
Quote:
refresh();
but have one getch() extra,its showing out put on the window.

without that getch() the program is getting terminated in falsh so we cant observe the out put .
my question is how its printing o/p on window without refresh().

As specified in the rules, you're not supposed to bump threads.

A little googling brought me to the curses functions echo() and noecho(), which enable and disable local echo respectively.
