i am still not able ot understand whats the error

the file consists of binary data. basically contains
32 complex nos.

they have to be stored in "in" array

error:   error in reading from file failed

:(
   1 #include<stdlib.h>
      2 #include<complex.h>
      3 #include<stdio.h>
      4
      5 int main()
      6 {
      7         FILE *fp;
      8         fp=fopen("test_data.dat","rb");
      9         int N=32,i=0;
     10         complex x,*in;
     11         in=malloc(sizeof(complex)*N);
     12         if (fread(in,16,32,fp) != 32)
     13          printf("error in reading from file
failed\n");
     14         else{
     15         for(i=0;i<N;i++)
     16           printf("%lf\t",*(in+i+0));
     17         }
     18         return 0;
     19 }

Not 32, but only 16.
