Tic Tac Toe - C++

[Wabtonio]

This is a console Tic Tac Toe game made with C++.

It's a two player game, and you type in the number for the space you want to put your letter in.

ScreenShot:


If you don't wanna compile it, here's the exe:

Wow

That's awesome.

Gw man

[cynick]

yea wd bro

[SargeRX8]

Very nice work man. Nice neat coding. Try in the future though not to use the goto function. It can be avoided.

[joshkent]

Nice and clean, as sarge said, it CAN be avoided

[kotso]

AHAH THAT IS AWESOME!

[SargeRX8]

Also i cant run the EXE, i got a configuration error.

[God]

Wish C had Boolean types, probs a cleaner way to do the else ifs but i cbf thinking of one (i'd do the exact same thing in my code).

Edit: cept personally id keep main() smaller with some unneeded aesthetic functions

[Khaless]

C++ has bool...

C has your very own:
typedef enum {false = 0, true = 1} bool;

[SargeRX8]

Would have been simpler to do a win function if he had used a 2D array? I remember doing something similar to this(it was a game where it scrambles the numbers on a grid and then you gotta sort em out and another game where you load an image like a puzzle and you gotta unjumble it) and used a 2D array and my check win function was i think alot shorter.

[Khaless]

Yeah, a 2D array might make it easier as you can break it into 3 cases, check rows, check cols and check diagonals.

But still a 1D approach really allows you to confuse people...

def check; [[1,1,1,0,0,0,0,0,0],[0,0,0,1,1,1,0,0,0],[0,0,0,0,0,0,1,1,1],[1,0,0,1,0,0,1,0,0],[0,1,0,0,1,0,0,1,0],[0,0,1,0,0,1,0,0,1],[1,0,0,0,1,0,0,0,1],[0,0,1,0,1,0,1,0,0]].each { |m| s = SyncEnumerator.new(@b, m); w = 0; s.each { |r| w += r[0] * r[1] }; if w.abs == 3; return w/3; end }; @b.each {|i| return false if i == 0}; return 0; end

** disclaimer: untested ...

But yeah, perhaps try to avoid the goto's as Sarge said.

NEXT:

A) Let user choose whether to play 1st or not
B) Have two difficulties - one you can win against, one you can only draw or lose against

(tictactoe is a dead draw with best play from both sides)

GOGOGO

[Khaless]

Do a Min-Max algorithm for it.
