U cemu gresim?!?

sledeci program ce da ti proveri da li postoji korisnik, tj,
dali postoji PATH LOC/korisnik, i da izlista pronadjeni fajl,

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAXPUT 128
#define LOC "/var/spool/mail/"
#define LOCSIZE 16 /* duzina stringa LOC */

int main () {


FILE *pf;

char data[4096];
char ime[MAXPUT-LOCSIZE];
char imes[MAXPUT] = LOC;

printf ("\nIme korisnika: ");
scanf("%s", ime);
strcat(imes, ime);

if ((pf = fopen(imes, "r")) == NULL)
printf("\nKorisnik %s nepostoji !!!\n", ime);
else {
while (!feof(pf)) {
fscanf(pf,"%s",data);
printf ("%s\n",data);
}
fclose(pf);
}
return EXIT_SUCCESS;
}
