     if (fptr != NULL) {
          puts("File numbers.dat is opened successfully.");
          m = fscanf(fptr, "%d", &n);
          while(m != EOF){
               printf("%d ", n);
               m = fscanf(fptr, "%d", &n);
          }
          printf("\n");
          k = fclose(fptr);
          if(k == -1)
              puts("File-closing failed");
          if(k == 0)
