This is what I use to generate passwords.  Fancy, no, but, it works.
You can muck with valid to both change what you put in the entry and
the distribution (want more numbers, put them in more than once, etc).
It seems, however, like you have a lot of other problems like
making the rest of the password entry.  May I suggest awk?

---------------------------------------------------------------------

/* rpw.c -- random password generator */
void strand();
long time();
int rand();

char valid [] =
	{"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890"};

main()
	{
	int i;

	srand((unsigned)time((long*)0));
	for(i=0; i<8; i++)
		putchar(valid[rand() % sizeof(valid)]);
	putchar('\n');	
	}
