Reading external File or File processing in C

[akinidu]

Hi!

Below is the code which can be use to read and display a simple extrenal file in C...But I am wondering How can i use pointers here and access this file via pointer

 
/* Display contents of a file on screen. */
# include "stdio.h"
int main(void )
{
     FILE *fp ;
     char ch ;
     fp = fopen ( "sinfft.dat", "r" ) ;
     while ( 1 )
     {
          ch = fgetc ( fp ) ;
          if ( ch == EOF )
                break ;
          printf ( "%c", ch ) ;
     }
     fclose ( fp ) ;
     return 0;
}
 
 
 

So the program above displaying content on screen, now assuming my .dat file has 500 rows and 1 column..how can use pointer and make every thing in a array which can be processed further
[code]
Below is what i think should work but its wrong

/* Display contents of a file on screen. */
# include "stdio.h"
int main(void )
{
 
     int *in;
     array[500]={};
     in=&array;
     FILE *fp ;
     char ch ;
     fp = fopen ( "sinfft.dat", "r" ) ;
     while ( 1 )
     {
          ch = fgetc ( fp ) ;
          if ( ch == EOF )
                break ;
          printf ( "%c", ch ) ;
     }
     fclose ( fp ) ;
 
     for(in=0;in<=500;*in++);{
      printf("Array is %f", in);
}
 
return 0;
}
 
 

So how should i proceed it ! I think i need to go through pointers again!
