C++ ifstream Reads the TXT file backwards, printing each character

#include <fstream.h>
#include <stdlib.h>
#include <stdio.h>
ifstream fp;// w w w .java2  s .c  o m
void main()
{
   int ctr;   // Steps through the 26 letters in the file.
   char in_char;
   fp.open("ALPH.TXT", ios::in);
   if (!fp)
   {
      cout << "\n*** Error opening file ***\n";
      exit(0);
   }
   fp.seekg(-1L, SEEK_END);   // Point to last byte in the file.
   for (ctr = 0; ctr < 26; ctr++)
   {
      fp >> in_char;
      fp.seekg(-2L, SEEK_CUR);
      cout << in_char;
   }
   fp.close();
   return;
