Can anyone explain to me why printf() wont immediately print to the screen
after calling clrscr(), unless I use fflush(stdout) first? It works fine
without the fflush() on my Borland compiler.
 
example:
	// this seems to jump straight to getch() without printing "hello
world" first. When the program ends, it then prints out.

#include <stdio.h>
#include <conio.h>

int main(void)
	{
	clrscr();
	printf("Hello World!");

	getch();   // or delay(1000); or while(!kbhit()){}
	return(0);
	}
	// if I use fflush(stdout) after clrscr(); then it prints
immediately. It seems that once I've called clrscr() I have to call
fflush() every time I want to printf() something. Am I doing something
wrong?
Any help would be appreciated. Thanks.
Mike. --
