size of a file

[seemant_sun]

write a program to find size of a file without traversing it character by character?

will anybody tell me the logic hw to approach it

is there any trick involved

[ArkM]

Use fseek and ftell functions from <stdio.h>.

[csurfer]

Every file ends with an EOF character.Find out what the functions which ArkM has stated does and use the above information and you are done.

Even using fseek()/ftell() might be an approximate answer.

are you using *nix?

#include <stdio.h>
#include <sys/stat.h>

int getFileSize(char *filename, long *filesize)
{
   struct stat filestats;              

   if (stat(filename, &filestats) < 0) {
   { 
      perror(filename);
      return 0; 
   } 
   else
      *filesize = filestats.st_size;

   printf(" The size of %s is %ld bytes (%3.1f KB)\n", filename, *filesize, (*filesize / 1024.0) );
   return 1;
}

Those C functions may not work with huge files -- files that are larger than 2 gig. In MS-Windows win32 api functions would be needed to get the file size of huge files. I don't know about *nix or MAC
