}
}
}
for ( i = 0 ; i <10 ; i++ )
printf("the sorted array is: %d \n", &arr[i]);

The problem is in your scanf statement. Scanf needs a reference and "arr[i]" is already de-referenced. You need to prefix it with "&".

You probably wanted those loops to be ... ; i < 9; ... and ... ; j < 10; .... Also this algorithm is not a merge sort, it's a bubble (down) sort.
