Xcode writting/reading file problem

Question

Hi,
im using xcode to compile in c  language, but im having problem with files, writting/reading simply doesnt work (to be exact i have to say that i copied source code to dev-c++ on windows platform to check the code and it works normaly as it should) any suggestions?
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int main (int argc, const char * argv[])
  char tekst[]="tujesttekstktorychchcezapisacdopliku";
          char tekst2[20];
  FILE *plik;   /*r=read, w=write, rwx-obydwachyba, wb-tryb binarny*/
          if ((plik=fopen("text", "w"))==NULL)
  printf("plik nie zostal otworzony");
          fprintf(plik, "%s" ,tekst);  /*wpisanie tekstu*/
          fscanf(plik, "%s",tekst2);
  printf("tekst2: %s\n", tekst2);
          if (fclose(plik)!=0)
  printf("blad przy zamykaniu");
    printf("Hello, World!\n");
    return 0;
the result of this program is "hello world" ONLY.
file is clean, same thing with test2 variable.
in copied code opening mode is "w" but ive checked almost all options ofc including binary file modes (both doesnt work)
any suggestions?

while( (len = in2.read(b,0,1024)) != -1 )
bytcount=bytcount+1024;
inFile.write(b,0,1024);
} This is where you go wrong ... suppose you're reading, say 100 bytes instead of the maximum 1024;
you're still writing 1024 bytes instead of those 100 bytes; your 'bytcount' goes berzerk too. Have a
look at this -- while( (len = in2.read(b,0,1024)) != -1 ) {
   bytcount=bytcount+len;
   inFile.write(b,0,len);
} kind regards,
