If you want to use NCURSES / CURSES, it's a bit complicated.

Otherwise, just output %c (the character) 0x07, BEL, which
generates an audible bell, or beep.

/* beepflash.c

#include <stdio.h>
#include <ncurses.h>

int main(int argc, char *argv[])
{
	initscr();
	cbreak();
	noecho();
	nonl();
	intrflush(stdscr, FALSE);
	keypad(stdscr, TRUE);
	start_color();

	printf("beep: %d\n", beep());
	fflush(stdout);

	printf("flash: %d\n", flash());
	fflush(stdout);

	return 0;
