[Loregoreth]

I have completed my third game, Tic-Tac-Toe. I think the AI is unbeatable, well I haven't beat it yet. It took about a month to finish in C++. If you wish to download it.

I got error when trying to play that at school.

My OS is Finnish so I dont know how to say that Error-report in english but it says something like "initializing failed (0xc0000135)"

That's an awfull lot of code duplication. I'm pretty shure you could use a loop to avoid that.

No AI in the world is unbeatable. It took me 2 tries to win.

Pretty easy actually. Nice game.

I think he was going for readability, but of course in practice this method would be a nightmare to maintain on a larger project. Nice work though, keep at it.

I got error when trying to play that at school.

My OS is Finnish so I dont know how to say that Error-report in english but it says something like "initializing failed (0xc0000135)"

Sounds like a memory error, generally a 0xc.... error has to do with mem. Kind of interesting that a term. based program would come up with that.

No AI in the world is unbeatable.

It doesn't take a genius (far from it) to play Tic-Tac-Toe perfectly. If both players play perfectly, it is a draw. Always. So if his ai was perfect (which I guess it isn't, in which case I'm shocked he never beat it) it would be unbeatable. The best you could do is draw.

I think he was going for readability

In my opinion,it is more readable if a loop shows you wich variables are changing and in what order. Otherwise you need to extract that information from n nearly identical code blocks. Not readable.

When I said readable I meant neat not small. For instance i wrote it like this:

if (box[8].fill == 'X'&& box[4].fill == ' ')
{
box[4].value += 3;
}


instead of like


if (box[8].fill == 'X'&& box[4].fill == ' ') box[4].value += 3;


this or


if (box[8].fill == 'X'&& box[4].fill == ' ')
box[4].value += 3;


this.

Its seems i also forgot to make sure the AI checked for double win.

PS: I only played it three times so I didn't have time to continue looking for a way to win.
