      fp=fopen("/home/smec/Desktop/hello.txt","r");
      if(fp==NULL)
      {
            printf("File does not exist..");
      }
      fseek(fp,0,SEEK_END);
      pos=ftell(fp);
         i=0;
      while(i<pos)
       {
            i++;
            fseek(fp,-i,SEEK_END);
            ch=fgetc(fp);
            printf("%c",ch);
