[newbie][code] do_whois

yep, another whois newbie

my problem, I think, is that I dont know how to properly declare a char *buf statement, and to use an array...

I must apoligize, I'm just learning c

and here is the errors generated at compile:

act.informative.c: In function `do_whois':
act.informative.c:1148: warning: excess elements in array initializer
act.informative.c:1148: warning: (near initialization for `immlevels')
act.informative.c:1154: warning: `buf' might be used uninitialized in this function

here is my do_whois code from act.informative.c:

const char *immlevels[LVL_IMPL - (LVL_IMMORT-1)] = {

   struct char_data *victim = 0;
   struct char_file_u tmp_store;
   char *buf;

   if (!*argument) {
   send_to_char(ch, "Who?\r\n");
} else {
   CREATE(victim, struct char_data, 1);
   if (load_char(argument, &tmp_store) > -1) {
   store_to_char(&tmp_store, victim);
   *buf = '\0';

   if (GET_LEVEL(victim) >= LVL_IMMORT)
   sprintf(buf + strlen(buf), "%s %s %s\r\n", immlevels[GET_LEVEL(victim)-LVL_IMMORT], GET_NAME(victim), GET_TITLE(victim));

   else if (GET_LEVEL(victim) < LVL_IMMORT)
   sprintf(buf + strlen(buf), "Level %d %s- %s %s\r\n",
   GET_LEVEL(victim), CLASS_ABBR(victim), GET_NAME(victim), GET_TITLE(victim));

   send_to_char(ch, buf);
} else {
   send_to_char(ch, "There is no such player.\r\n"); }

could anyone explain how to declare/fix these?
