  Well, try:

#include <stdlib.h>
#include <stdio.h>
#include <curses.h>

int
main(int argc,char** argv)
{
    /* in curses(3X) manual page... */
    initscr();

    if (beep() !=3D OK)
        printf("No OK\n"); fflush(stdout);
    if (flash() !=3D OK)
        printf("No Flash\n"); fflush(stdout);
	return 0;
}

  And read the curses manual page, you forgot to init
the screen.
