You could always use setvbuf to flush out the stdout.
eg....

void main(void)
 {
        setvbuf(stdout, NULL, _IONBF, 0);
 	printf("Hello world");
 	getch();
 }

instead of ...

void main(void)
 {
printf("Hello world");        
 	flush();
 	getch();
 }

where you have to flush each time you use the printf function. (kinda
silly)
