This one's more inclined to secure, really random Passwords which
might not be easy to learn:

penthesilea:/home/TI/bern% cat c-*/password.c
#include <sys/types.h>
#include <sys/time.h>

char lowercase()
{  return random()%26+'a';
}

char alphanum()
{  long num;

   num=random()%62+'0';
   if (num>'9') num+='A'-':';
   if (num>'Z') num+='a'-'[';
   return num;
}
   
main()
{  long i, j;
   char pass[9];
   
   i=(long)time((time_t)0);
   srandom(i);
   j=random()^i;
   srandom(j);
   sleep(1);    /* Required or next Call will get same time() */
   
   pass[0]=lowercase();
   for (i=1;i<8;i++) pass[i]=alphanum();
   pass[8]='\0';
   
   printf("%s\n",pass);
}
penthesilea:/home/TI/bern% password
xgPA3f8V
penthesilea:/home/TI/bern% password
eIuaT6wX

Note that the generated Passwords will *probably* pass 2.x Restrictions
(i.e., contain a Digit), but not 100% sure.
