Sorry boys -- Ive made a mistake.

printX(7);

*           *
  *       *
    *   *

Not going to bother writing code but the process is trivial
Looping i over j, Asterisks go in the j = i mod N and it's symmetrical position(N-1 - i mod N).

Everything else is space.

what about users putting 1 or 2 in?

>>59242914

doesnt compile

>>59242941

ugly as shit kys

>>59242914
What programming language is this?

>>59241990
what should print(even_number) print?

>>59244865
F

>>59242871
well here it is in Dlang

import std.stdio;
import std.conv;

void asciiX(int size)
{
    for(int y = 0; y < size; y++)
    {
        for(int x = 0; x < size; x++)
        {
            if(x == y % size || x == size - 1 - y % size)
            {
                write("*");
            }
            else
            {
                write(" ");
            }
        }
        writeln();
    }
}

void main(string[] args)
{
    if(args.length < 2)
    {
        writeln("Not enough arguments");
        return;
    }
    asciiX(to!int(args[1]));
}

Sadly I don't know enough Dlang yet to simplify it.

Please rate, I'm just a haskell beginner, took me approx 10 minutes because I do not code in haskell that often...

Also, it feels very hacky.
