the output is buffered.  i don't see a requirment to flush
stdout or any other output stream in c99 or posix standard for
fgetc, though i may have missed something.  getchar is
defined in terms of fgetc.  i would think this code would
reliably do what you wish:

#include<stdio.h>
int
main(void)
{
	printf("\nprompt");
	fflush(stdout);
	getchar();
	return 0;
}
