What position is the letter A? Let's use a lookup table!

Does this count? Converting dates to the Roman equivalent[^] The database is no longer available (thankfully, it was 75MB!) and sadly, nobody got the joke... :sigh:

That was written just before you stopped drinking? Yes?

That did have a point. It was actually quite a funny point.

Rotted Frog

yes, we need to add 'a' to 'z' in as well. I'll assign it out to one of my team to fix immediately.

Rotted Frog

Well done. You get all the bonus points.

It was written as a follow up to Converting numbers to the word equivalent. [^] since we were getting a lot of "Roman numbers" homework in QA back then.

So you'd moved off the booze by then; onto the class 'A' drugs. :laugh:

And it gets better... Just noticed the next class on from that one:

public class ZeroBasedAlphabetPositionMap
{
private static Dictionary<char, int> alphabet = new Dictionary<char, int>();

static ZeroBasedAlphabetPositionMap()
{
    alphabet.Add('A', 0);
    alphabet.Add('B', 1);
    alphabet.Add('C', 2);
    alphabet.Add('D', 3);
    alphabet.Add('E', 4);
    alphabet.Add('F', 5);
    alphabet.Add('G', 6);
    alphabet.Add('H', 7);
    alphabet.Add('I', 8);
    alphabet.Add('J', 9);
    alphabet.Add('K', 10);
    alphabet.Add('L', 11);
    alphabet.Add('M', 12);
    alphabet.Add('N', 13);
    alphabet.Add('O', 14);
    alphabet.Add('P', 15);
    alphabet.Add('Q', 16);
    alphabet.Add('R', 17);
    alphabet.Add('S', 18);
    alphabet.Add('T', 19);
    alphabet.Add('U', 20);
    alphabet.Add('V', 21);
    alphabet.Add('W', 22);
    alphabet.Add('X', 23);
    alphabet.Add('Y', 24);
    alphabet.Add('Z', 25);

}

public static int Position(char letter)
{
    return alphabet\[letter\];
}

}

How about adding another lookup that gets the uppercase equivalent of a lowercase letter?

Even more bonus points for a pointless lookup table for not being able to actually do a lookup :laugh:

AlphabetPositionMap seems to have a brother called ZeroBasedAlphabetPositionMap[^]. Yes, it is missing lowercaps variants, meaning there should at least be four of these methods. And globalization is missed completely. Scheiß drauf.

I thought I had a more useless lookup table, but I was wrong

private static Dictionary alphabet = new Dictionary();
static AlphabetPositionMap()
{
alphabet['A'] = 'A';
alphabet['B'] = 'B';
// you get the idea
}

I am wrong because it is only a small step from this code to creating an Enigma machine in software, which I believe had some amount of use a few years back. Failed at being useless :sigh:

... the map is static...

I've noticed that you do not cover lowercase numbers.

There is a seperate uppercase number lookup table for that ! :laugh:
