Note that this program will almost certainly crash if you try 
to run it, since modern computers do not allow programs to read 
and write arbitrary memory locations.

I wonder if the question was more like intended to display the 
value using pointers, ie:

import std.stdio;

void main(){
    int i;
    readf("%d\n", i);
    int *p = &i;
    writeln(*p);
}

Because accessing arbitrary memory location seems very weird.
